For the precise jet "p attern recognition"\, highly granular calorimeters are required. They have being developed by the CALICE collaboration starting from the beginning o f 2000's. The most demanding requirements are for the electromagnetic calo rimeter (ECAL).\nThe silicon-tungsten (SiW) ECAL technology\, though expen sive\, provides the best performance with an excellent granularity. We sha ll discuss the R&D and the recent results in this field in the talk.\n\nIn 2005-2012\, CALICE collaboration has built and tested the "physical proto types" of highly granular calorimeters to test PFA approach. We report the recent studies performed in 2016-17 on the recognition of two close by el ectromagnetic and electromagnetic-hadronic showers obtained with the event mixing\, and also on the tests of the hadronic interaction models with Si W ECAL physical prototype.\n\nFrom 2012 until present\, the SiW ECAL group develops the new generation of the prototypes\, called "technological"\, with fully embedded electronics. It should be suitable for the future e+e- high energy collider like ILC. A similar technology has been approved for the phase II CMS calorimeter endcaps upgrade (HGCAL project) and is also considered for the ATLAS preshower upgrade (HGTD project) and the LHCb inn er ECAL upgrade. Although the LHC\nupgrade projects will be briefly mentio ned\, the main focus in the talk will be on the development and the optimi zation for ILC. The recent test beam results at SPS in CERN will be discus sed in detail.\n\nhttps://indico.inp.nsk.su/event/8/contributions/1590/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1590/ END:VEVENT BEGIN:VEVENT SUMMARY:TPC status for MPD experiment at NICA project DTSTART;VALUE=DATE-TIME:20170228T051500Z DTEND;VALUE=DATE-TIME:20170228T053500Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1591@indico.inp.nsk.su DESCRIPTION:Speakers: Sergey Movchan (JINR)\nThis report presents:\n- MPD and TPC configurations\;\n- the main geometrical parameters and features of TPC\;\n- tooling for TPC assembly\;\n- design of readout chamber bas ed on MWPC and frontend electronics\;\n- description of TPC subsystems (g as\, cooling\, laser calibrarion) and its status\;\n- status of jobs on i ntegration of TPC into MPD.\n\nhttps://indico.inp.nsk.su/event/8/contribut ions/1591/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1591/ END:VEVENT BEGIN:VEVENT SUMMARY:Data Aquisition System for the PENeLOPE Experiment using the Unifi ed Communication Framework DTSTART;VALUE=DATE-TIME:20170303T051000Z DTEND;VALUE=DATE-TIME:20170303T053000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1592@indico.inp.nsk.su DESCRIPTION:Speakers: Dominic Gaisbauer (Institute for Hadronic Structure and Fundamental Symmetries\, TU Munich)\nPENeLOPE is a neutron-lifetime ex periment aiming for high precision by counting neutrons and decay protons. The proton detector consists of about 1250 Avalanche Photodiodes (APDs) w ith a total active area of 1225$~$cm$^2$. The detector and electronics wil l be operated on a high electrostatic potential of -30$~$kV\, in a magneti c field of 0.6$~$T and at a temperature of 77$~$K. The electronics include low-noise preamplifiers\, CR-RC shapers\, ADCs and FPGAs. Each FPGA reads out 96 12-bit SAR-ADCs with 1$~$MSps in parallel. We developed a firmware for the FPGAs including a self-triggering readout with continuous pedesta l calculation and configurable trigger threshold.\nThe data transmission a nd configuration is done via the Unified Communication Framework (UCF) we developed at the Technical University of Munich. UCF is a unified network protocol developed for FPGAs with built-in high-speed serial interfaces. I t provides up to 64 different communication channels via a single serial l ink. One channel is reserved for timing and trigger information\, the othe r channels can be used for slow-control interfaces and data transmission. All channels are bidirectional and share network bandwidth according to as signed priority. The timing channel distributes messages with fixed latenc y and low jitter (about 20$~$ps) in one direction. From this point of view the protocol implementation is asymmetrical. The framework supports point -to-point connections and star-like 1:n topologies. The star-like topology can be used for front-ends with low data rates and time-distribution syst ems. In this topology\, the master broadcasts information according to ass igned priorities\, the slaves communicate in a time-sharing manner to the master. \n\nThe project is supported by the Maier-Leibnitz-Laboratorium (G arching)\, the Deutsche Forschungsgemeinschaft and the Excellence Cluster "Origin and structure of the Universe".\n\nhttps://indico.inp.nsk.su/event /8/contributions/1592/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1592/ END:VEVENT BEGIN:VEVENT SUMMARY:First results from the ATLAS-GaAsPix radiation monitoring system DTSTART;VALUE=DATE-TIME:20170228T100000Z DTEND;VALUE=DATE-TIME:20170228T110000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1593@indico.inp.nsk.su DESCRIPTION:Speakers: Mikhail Demichev (JINR)\nThe ATLAS-GaAsPix system is a network of GaAs:Cr-based Timepix pixel detectors installed in various p oints of the ATLAS detector in the framework of the collaboration between JINR\, IEAP CTU\, CERN and Tomsk State University. The ATLAS-GaAsPix proje ct provides installation of 10 Timepix detectors (5 singles\, 5 twins) wit h GaAs:Cr sensors nearby Timepix detectors of the ATLAS-TPX system. First three detectors of the system were installed during YETS 2015-2016 and hav e successfully functioned during the LHC operation in 2016.\n\nIn this wor k we present the first results obtained with ATLAS-GaAsPix detectors inclu ding the estimation of radiation fluxes in the ATLAS cavern for different particles.

The versatile detector system will enable u s to study open questions in hadron physics\, by doing charmonium spectros copy with precision measurements of mass\, width and decay branches\, inve stigating possible exotic states\, search for modifications of charmed had rons in nuclear matter and gamma-ray spectroscopy of hypernuclei by using antiprotons on a cluster jet or a pellet target in the momentum range of 1 .5 to 15 GeV/c.\n\nThe barrel-TOF subdetector is one of the outer layers o f the multi-layer design of the PANDA barrel. It is designed with a minima l material budget in mind mainly consisting of 90x30x5 mm$^3$ thin plastic scintillator tiles read out on each end by a serial connection of 4 SiPMs . 120 such tiles are placed on 16 2460 x 180 mm$^2$ PCB boards forming a b arrel covering an azimuthal angle from 22.5° to 150°. The detector is de signed to achieve a time resolution below 100 ps (sigma) which allows for good event separation as well as particle identification below the Cherenk ov threshold via the time-of-flight\, simultaniously providing the interac tion times of events. The current prototype achieved ~60 ps\, well below t he design goal.\n\nThe R&D is in a matured stage and a technical design re port is currently being reviewed by the collaboration.

In case scintillation detectors are used\ , this often means such applications require scintillators with unique cha racteristics\, at least on one or two parameters. Examples of such require ments are: high transparency and radiation hardness of PbWO4 crystals for LHS CMS and ALICE detectors and isotopic purity and extra-low natural radi oactivity background of CaMoO4 crystals for Y2L AMoRE detector.\n \nTo rea ch the necessary scintillator performance special attention should be paid to chemical composition of raw materials. Development of a pure substance technology includes such components\, as finding suitable analytical tech niques\, development of purification procedures\, scaling these procedures to technological processes and establishing control methods. There are so me common approaches\, however\, every raw material compound purification is a special task. Developing a raw material specification is a separate p roblem as well\, and it usually takes extended experimental work.\nIn this report we summarize our experience on a development and production of hig h purity raw materials for high performance scintillators\, such as PbWO4\ , CaMoO4 and polycrystalline garnet-based scintillators.\n\nhttps://indico .inp.nsk.su/event/8/contributions/1595/ LOCATION:Budker Institute of Nuclear Physics URL:https://indico.inp.nsk.su/event/8/contributions/1595/ END:VEVENT BEGIN:VEVENT SUMMARY:Polycrystalline Scintillators for Large Area Detectors in HEP Expe riments DTSTART;VALUE=DATE-TIME:20170301T045500Z DTEND;VALUE=DATE-TIME:20170301T051500Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1596@indico.inp.nsk.su DESCRIPTION:Speakers: Georgy Dosovitskiy (Institute of Chemical Reagents a nd High Purity Chemical Substances\, IREA\, NRC "Kurchatov Institute")\nFu rther physical programs at the LHC will require a significant increase of the accelerator luminosity throughout the High Luminosity phase of LHC. Du ring this period\, charged hadrons and neutrons with fluences higher than 1014 p/cm2 per year in the largest pseudo-rapidity regions of the detector s will have a non-negligible influence on the radiation damage of material s. Moreover\, with the increasing activation of the experimental equipment \, it will become more difficult to periodically replace and maintain the detector components. Therefore\, the selection of materials for new detect ors to be used at the upgrade of experimental setup requires a more reliab le assessment of the risks of detector failures due to severe radiation da mage.\nY3Al5O12:Ce (YAG:Ce) crystal was found to be one of the most radia tion hard scintillation materials. However\, production of YAG:Ce in a sin gle crystalline form is costly because crystal growth is performed at tem perature near 1900 °C with a very low rate of transformation of a raw mat erial into a crystal. As an alternative solution to the single crystalline option we propose YAG:Ce based polycrystalline scintillation materials\, obtained by cheaper chemical routes. We have prepared and tested two varia nts: 1) a composite material\, composed of large sized grains\, packed and glued together into a translucent body with density up to 50% of the sing le crystal\; 2) sintered translucent ceramic body with density ~98% of the theoretical density. As all components of composite modules are selected to be radiation hard\, such technology can be considered a suitable option to replace plastic scintillators in a region of a detector where high rad iation hardness is mandatory. Here we report the results of a comparative tests of the YAG:Ce single crystals and composite modules obtained by diff erent approaches.\nWork was supported by Ministry of Science and Education of Russian Federation\, subsidy agreement № 14.625.21.0033 dated 27.10. 2015\, project identifier RFMEFI62515X0033.\n\nhttps://indico.inp.nsk.su/e vent/8/contributions/1596/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1596/ END:VEVENT BEGIN:VEVENT SUMMARY:Radiation damage in silicon photomultipliers exposed to neutron ra diation DTSTART;VALUE=DATE-TIME:20170228T100000Z DTEND;VALUE=DATE-TIME:20170228T110000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1597@indico.inp.nsk.su DESCRIPTION:Speakers: Adriaan Heering (University of Notre Dame (Notre Dam e))\, Yury Musienko (University of Notre Dame (Notre Dame)/INR RAS (Moscow ))\nWe report on the measurement of the radiation hardness of newly develo ped silicon photomultipliers (SiPMs) manufactured by Hamamatsu Corporation (Japan).

In this regard\, particularly relevant is the problem of calibration of detectors\nfor dar k matter\, and low-energy neutrinos\, especially in the field of low energ y of the recoil\nnuclei - less than 10 keV.\n\nIn Budker Institute of Nucl ear Physics we measured ionization yields of nuclear recoils in liquid arg on using a two-phase Cryogenic Avalanche Detector (CRAD) with electrolumin escence (EL) gap\, operated in argon doped with a minor (49 ± 7 ppm) admi xture of nitrogen at 87 K and 1.00 atm. The EL gap was optically read out using cryogenic PMTs located on the perimeter of the gap. We used DD gener ator to produce neutrons with 2.45 MeV energy.\n\nhttps://indico.inp.nsk.s u/event/8/contributions/1604/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1604/ END:VEVENT BEGIN:VEVENT SUMMARY:Study of proportional electroluminescence in two-phase argon DTSTART;VALUE=DATE-TIME:20170228T100000Z DTEND;VALUE=DATE-TIME:20170228T110000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1605@indico.inp.nsk.su DESCRIPTION:Speakers: Ekaterina Shemyakina (Budker Institute of Nuclear Ph ysics SB RAS)\nThis work was performed in the course of the development of a two-phase Cryogenic Avalanche Detector (CRAD) in Ar for dark matter sea rch and low energy neutrino experiments.

This process was theoretically predicted more than 40 years ago by the Standard model of particle physics but has not been observed yet beca use of lack of the detection technique of the events with the low energy d eposition in massive (more than several dozens of kg) targets: the energy of nuclear recoil from the neutrino scattering in detector is in the keV- and sub-keV- energy ranges. This can be done with a technology of particle detection by means of a two-phase emission detector proposed in Russia an d well worked out in the experiments on search for dark matter. The RED-10 0 two-phase xenon emission detector and proposed experiment with it at the Kalinin nuclear power plant (KNPP) is described in this talk.

There fore\, the installation of a chamber in that position would allow track re construction beyond the calorimeter at higher pseudorapidity\, increasing the muon system's acceptance and improving the tagging of high-eta muons\, besides improving muon trigger. Main challenges to such installation are the high particle flux to be substained\, high radiation tolerance\, and f itting a multi-layered detector in a reduced available space (less than 30 cm). Micropattern Gaseous Detectors (MPGDs) show promising performances r esponding to the most severe constraints posed by High Energy Physics (HEP ) experiments. They use small amplification regions - of the order of tens of microns - allowing for a high rate capability\, a very good spatial re solution and radiation tolerance. Lots of MPGDs with different geometries have been developed and tested. An example is the Gas Electron Multiplier (GEM) detector\, using copper clad kapton foils on which microscopic holes \, hundreds microns apart\, have been chemically etched. The cathode and t he anode electrodes close the foils that are conveniently spaced to create drift\, transfer and induction gaps. A new configuration – back to back - of such a device is presented with the aim of developing a compact size multi-GEM detector. It is composed by two independent stacked triple GEM detectors\, positioned with the anodes toward the outside. In this wa y\, they can share the same cathode\, placed at the center of the system\, allowing to reduce the total detector's thickness since a single cathode and a single external frame are used. A first prototype has been produced and characterized with an X-Ray source and muon beams. First results on it s performance will be presented.\n\nhttps://indico.inp.nsk.su/event/8/cont ributions/1608/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1608/ END:VEVENT BEGIN:VEVENT SUMMARY:Neutrino detectors for oscillation experiments DTSTART;VALUE=DATE-TIME:20170301T080500Z DTEND;VALUE=DATE-TIME:20170301T083000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1609@indico.inp.nsk.su DESCRIPTION:Speakers: Yury Kudenko (Institute for Nuclear Research)\nRecen t progress in the development of the detectors for neutrino oscillation ex periments will be presented.

It is a fixed target experiment in the antiproton storage ring HESR. Main topics of the PANDA physics program are the search for new and predicted states and the precise measurement of the line shape by the ener gy scan method. Crucial for these measurements is the precise determinatio n of the luminosity at each energy point for normalization of the data tak en.\n\nTo determine the luminosity with a precision of better than 3$\\\,$ %\, PANDA will implement a tracking device to reconstruct elastically scat tered antiprotons near the non interacting antiproton beam. It will consis t of four planes of thinned silicon sensors (HV-MAPS) for the reconstructi on of the tracks. HV-MAPS (High Voltage Monolithic Active Pixel Sensor) is a pixel sensor combining frontend electronics with the actual sensitive m aterial on one chip. To increase the signal speed and the radiation tolera nce a reverse bias voltage of 60$\\\,$V is applied. The whole detector sys tem will be operated in vacuum in order to reduce the systematic uncertain ty due to multiple scattering. In addition the setup has to have a very lo w material budget. Therefore the 50$\\\,$µm thick sensors are glued on bo th sides of a 200$\\\,$µm CVD diamond. These modules are clamped in a hol ding and cooling structure.\n\nThis presentation will discuss the technica l design of the tracking detector for the luminosity measurement and its c hallenges like cooling\, mechanical support structures\, differential pump ed vacuum system\, and the sensors themselves.

For the upgrade of the inner detector\, planned for 2018\, a lightweight tracker based on an innovative Gas Electron Multiplier (GEM) cylindrical d etector is now under development. The analogue readout of the CGEM enables the use of a charge centroid algorithm to improve the spatial resolution to better than $130\\ \\mu$m while loosening the pitch strip to $650\\ \\m u$m\, which allows to reduce the total number of channels to about 10 000. \nThe channels are readout by 160 dedicated integrated 64-channel front-en d ASICs\, providing a time and charge measurement and featuring a fully-di gital output. \n\nThe energy measurement is extracted either from the time -over-threshold (ToT) or the 10-bit digitisation of the peak amplitude of the signal.\nThe time of the event is generated by quad-buffered low-power TDCs\, allowing for rates up to 60 kHz per channel. The TDCs are based on analogue interpolation techniques and produce a time stamp (or two\, if w orking in ToT mode) of the event with a time resolution better than 100 ps . The front-end noise\, based on a CSA and a two-stage complex conjugated pole shapers\, dominate the channel intrinsic time jitter\, which is less than 5 ns r.m.s.. The time information of the hit can be used to reconstru ct the track path\, operating the detector as a small TPC and hence improv ing the position resolution when the distribution of the cloud\, due to la rge incident angle or magnetic field\, is very broad.\n\nEvent data is col lected by an off-detector motherboard\, where each GEM-ROC readout card ha ndles 4 ASIC carrier PCBs (512 channels).

The iTOP will identi fy\, with high precision\, charged hardons created in electron-positron co llisions at the SuperKEKB collider. With its timing resolution of less tha n 50 ps\, the iTOP will help searching for rare and previously unobserved physics events while minimizing effects of SuperKEKB beam backgrounds on t he reconstructed data. The iTOP is built as a 16-module barrel detector pl aced at Belle II between the Central Drift Chamber and the Electromagnetic Calorimeter. In the iTOP\, Cherenkov photon signals are collected by micr ochannel plate photomultiplier tubes. Sixty four (four per each iTOP modul e) 128-channel electronic Subdetector Readout Modules (SRMs) sample the co llected photon signals\, digitize them\, read out the digitized data\, and then forward them to the Belle II back-end data acquisition system. Every SRM is composed of five boards. Four of those boards carry application-sp ecific integrated circuits (ASICs) that perform sampling and digitization\ ; every board (the ASIC carrier board) has four 8-channel ASICs mounted on it. Sampling and digitization in each channel is done by a 16 x 32 (x 64) switched capacitor array using Wilkinson method. The ASIC carrier board\, in addition\, has a field-programmable gate array that reads out the digi tized data from the on-board ASICs. The fifth board of the SRM\, named as Standard Control Readout Data (SCROD) board\, collects data from the four ASIC carrier boards\, then buffer and forward them through an optical link to the back-end data acquisition system. The field-programmable gate arra y mounted on the SCROD board formats the data collected from the ASIC carr ier boards. The iTOP 8192-channel front-end electronic readout system was built and integrated at Belle II. In situ commissioning of the system is u nderway.

Austria)\nT he ALICE Collaboration is preparing a major detector upgrade for the secon d LHC shutdown (2019-2020). The LHC luminosity and collision rate from 202 1 onwards will considerably exceed the design parameters of the present AL ICE forward trigger detectors. Furthermore\, the introduction of a new Muo n Forward Tracker will significantly reduce the space available for the up graded trigger detectors. To comply with these conditions a Fast Interacti on Trigger (FIT) has been designed. The FIT will be the primary forward tr igger and will provide minimum bias trigger\, multiplicity trigger\, centr ality\, beam-gas event rejection\, collision time for the Time of Flight d etector (TOF)\, offline multiplicity and event plane determination. The FI T detector comprises of two subdetector systems\, T0+ and V0+. The T0+ con sists of two arrays of quartz radiators coupled to MCP-PMT sensors facing the interaction point. The V0+ detector is composed of a disk of plastic s cintillator segments\, optical fiber bundles\, and photosensors. In this c ontribution\, we will focus on the V0+ detector.\nThe V0+ detector require s high efficiency\, high dynamic range (1 – 500) particles\, radiation h ardness and must be compatible with 25 ns bunch spacing and ~ 1-2 MHz inte raction rate for pp collisions of the new LHC operation while keeping the time resolution of about 200 ps for a single particle. In order to fulfill these technical challenges\, a rigorous R&D work is ongoing. In this talk \, we will present the latest status of the R&D\, an optimization of scint illator material\, the choice of photosensors (SiPM\, Finemesh PMT\, and M CP-PMT)\, the design of the optical fiber bundles and the readout electron ics as well as an outlook.\n\nhttps://indico.inp.nsk.su/event/8/contributi ons/1624/ LOCATION:Budker Institute of Nuclear Physics URL:https://indico.inp.nsk.su/event/8/contributions/1624/ END:VEVENT BEGIN:VEVENT SUMMARY:Energy and time reconstruction algorithm of Belle II electromagnet ic calorimeter DTSTART;VALUE=DATE-TIME:20170228T100000Z DTEND;VALUE=DATE-TIME:20170228T110000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1644@indico.inp.nsk.su DESCRIPTION:Speakers: Alexander Bobrov (BINP)\nThe design luminosity of th e SuperKEKB collider in the BelleII \nexperiment at KEK is $8\\times10^{35 }$ $\\rm{cm}^{-2}\\rm{s}^{-1}$ or \n40 times larger than that of the previ ous KEKB collider with the\nBelle detector.

To pr ovide the best track reconstruction\, the trigger system must now import a ll available trigger primitives generated by Cathode Strip Chambers and by certain other subsystems\, such as Resistive Plate Chambers (RPC). In add ition to massive input bandwidth\, this also required significant increase in logic and memory resources. To satisfy these requirements\, a new Sect or Processor unit has been designed. It consists of three modules. The Cor e Logic module houses the large FPGA that contains the track-finding logic and multi-gigabit serial links for data exchange. The Optical module cont ains optical receivers and transmitters\; it communicates with the Core Lo gic module via a custom backplane section. The Pt Lookup Table (PTLUT) mod ule contains 1 GB of low-latency memory that is used to assign the final P t to reconstructed muon tracks. The µTCA architecture (adopted by CMS) wa s used for this design. The talk presents the details of the hardware and firmware design of the production system based on Xilinx Virtex-7 FPGA fam ily. The next round of LHC and CMS upgrades starts in 2019\, followed by a major High-Luminosity (HL) LHC upgrade starting in 2024. In the course of these upgrades\, the new Gas Electron Multiplier (GEM) detector and more RPC chambers will be added to the Endcap Muon system. In order to keep up with all these changes\, a new Advanced Processor unit is being designed. This device will be based on Xilinx UltraScale+ FPGAs. It will be able to accommodate up to 100 serial links with bit rates of up to 25 Gb/s\, and p rovide up to 2.5 times more logic resources than the device used currently . The amount of PTLUT memory will be significantly increased to provide mo re flexibility for Pt assignment algorithm.

A near detector complex (ND280) is used to constrain non-oscillated flux and hence predict the expected number of events in the far detector (Super-Kamiokande). The difference in the target material between the far (water) and near (scintillator\, hydrocarbon) detectors leads to the main non-cancelling systematic uncertainty for the oscillation analysis. In ord er to reduce this uncertainty a new water grid and scintillator detector\, WAGASCI\, has been proposed.\n\nMagnetized Iron Neutrino Detector (Baby-M IND) is Muon Range Detector (MRD) for WAGASCI experiment in T2K. The Baby- MIND modules are composed of magnetized iron and the long plastic scintill ators bars which are read out with wavelength shifting (WLS) fibers. Event reconstruction resides in selecting tracks above the certain threshold in length. Analyzing the vertex allow us to reconstruct the hadronic compone nt of interactions.\n\nNew frontend board CITIROC was created for readout of Baby-MIND.

These types of PMT are proposed for installation into the future double -phase cryogenic avalanche detector that is developed in the Laboratory of Cosmology and Particle Physics of the Novosibirsk State University jointl y with the Budker Institute of Nuclear Physics. \nCompact PMTs are planned to be installed at the side of the cryogenic vessel and they will detect electroluminescense in a high field region above liquid. 3 inch PMTs will be installed at the bottom of the cryogenic vessel in liquid Ar and they w ill detect primary scintillations from recoil nuclei as well as secondary scintillations. Main task of both PMT systems is to provide fast trigger signal. Therefore the PMTs have to distinguish between single electron and double electron signals to suppress effectively the background. \nEight R 11065 PMTs and eight R11410-20 tubes were tested and they all demonstrated excellent performance in terms of gain and relative single electron effic iency. All 3 inch PMTs showed maximal gain in liquid Ar above 5x10$^6$ and relative single electron efficiency above 95%. Compact R6041-506MOD tube s have different dynode system and thus their single electron energy reso lution and relative efficiency is much worse than that of 3 inch tubes. Fr om 21 two inch PMTs only 12 tubes were selected with acceptable relative s ingle electron efficiency higher than 70% at the maximal gain higher than 5x10$^6$.

Due to high intensity of the beam\, even a small amount of beam los s may cause cooling issue and serious damage to accelerator components and radiation sensitive equipment. The ultimate goal of a beam loss monitor s ystem at a high intensity beam is to identify the loss level and\, if poss ible\, the loss location and time structure and to be able to protect the machine at uncontrolled loss (detect the uncontrolled loss as soon as poss ible and shut down the accelerator in microsecond level). This requires th e beam loss monitor has fast response and excellent radiation resistance. The traditional ionization chamber\, plastic (liquid) scintillator+PMT\, P IN diodes etc has difficulties to satisfy all of the requirements.\n\nIn t his talk\, we will report the design and test results of a fast response a nd radiation-resistant scintillator detector as the beam loss monitor of h igh intensity beam at low energy part such as RFQ. The detector is consist ent of a 2cm x 2cm x 0.5 cm LYSO crystal readout by a 0.6 cm x 0.6 cm Sili con photomultiplier (SiPM). LYSO features high light yield\, short decay t ime\, relative dense and very good radiation resistance (2 orders of magna te higher than plastic scintillator). And SiPM has many advantages compare d to PMT. It is compact\, economy\, insensitive to magnetic field and has low working voltage\, good charge resolution and broad spectra response. T he detectors we constructed have been tested with various radioactive sour ces. The test results show that the detector has good sensitivity to photo n at energy range of a few keV to tens of MeV and charged particles with g ood linearity and energy resolution (23% for 60 keV X-ray). Two detectors (one parallel to and the other perpendicular to the beam) are installed ou tside of the vacuum chamber shell of a 800 MeV electron storage ring and t ested.

Cryogenic scintillating bolometer s are among the most promising detectors used for the investigation of rar e nuclear processes due to their excellent background rejection capabiliti es thanks to the simultaneous and independent\, double readout of heat and scintillation light induced by particle interaction in the crystal.\n The main goal of the CUPID-0 experiment is to demonstrate the feasibility of using scintillating bolometers to search for the neutrinoless double beta decay of several perspective isotopes (82Se\, 100Mo\, 116Cd and 130Te). 10 0Mo is among them due to its high energy transition (Qbb = 3035 keV)\, com parably high natural isotopic abundance (9.67%)\, possibility to be highly enriched by the ultra-speed gases centrifuges technology (up to 99.5%) an d a reasonable price for such type of enrichment. Different molybdenum-bas ed crystals were tested in the last decade for their potential application as scintillating bolometers. Among them\, the most promising are Li2MoO4\ , CaMoO4 and ZnMoO4. Despite of a significant progress in their developmen t\, there are a number of challenges to be met\, mainly caused by the high internal radioactive contamination and difficulties in the high quality l arge volume crystal production. However\, many of these problems can be om itted in case of PbMoO4 crystal produced from archaeological lead. \n Here we present results on the archPbMoO4 crystal performance produced from ar chaeological lead\, as a promising scintillating bolometer to search for t he neutrinoless double beta decay of 100Mo. For this purpose the archPbMoO 4 crystal has been characterized by chemical and optical methods\, and by means of cryogenic measurements.\n\nhttps://indico.inp.nsk.su/event/8/cont ributions/1635/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1635/ END:VEVENT BEGIN:VEVENT SUMMARY:The low energy beam profile monitor for the muon g-2/EDM experimen t at J-PARC DTSTART;VALUE=DATE-TIME:20170228T100000Z DTEND;VALUE=DATE-TIME:20170228T110000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1636@indico.inp.nsk.su DESCRIPTION:Speakers: Georgiy Razuvaev (Budker Institute of Nuclear Physic s)\nThe muon g-2/EDM experiment at J-PARC aims to measure the muon’s ano malous magnetic moment and electric dipole moment with high precision by u tilizing an ultra-cold muon beam.

The main JUN O challenge is to achieve a record energy resolution\, ~3% at 1MeV of ener gy released in the LS\, which is required to perform the neutrino mass hie rarchy determination.\nAbout 20’000 large 20” PMTs with high Photon De tection Efficiency (PDE) and good photocathode uniformity ensure about 80% surface coverage of JUNO detector.\nThe JUNO collaboration is preparing e quipment for the mass tests of all PMTs using 4 dedicated containers. Each container consists of 36 drawers. Each drawer will test a single PMT. Thi s approach allows us to test 144 PMTs in parallel. The basic measurement i n the container will be the PMT response during illumination of its photoc athode by the uniform light of a small intensity. All of the 20000 PMTs wi ll undergo the container test. \nFor sampled tests of PMTs also a dedicate d scanning system was constructed that allows us to study a variation of t he PDE over the whole PMT photocathode surface. Recently a sophisticated l aboratory for the PMT testing was built. It has a dark room where the scan ning station is housed. The core of the scanning station is a rotating fra me with 6 LED sources of calibrated short light flashes that are placed al ong the photocathode surface covering zenith angles from the top of a PMT to its equator. It allows testing of individual PMTs in all relevant aspec ts by scanning the photocathode and identifying any potential problem.\nTh e collection efficiency of a large PMT is known to be very sensitive to th e Earth Magnetic Field (EMF)\, therefore\, understanding the necessary lev el of EMF suppression is crucial for the JUNO Experiment.

Two basic configuration s for LAr TPC are considered: a single phase and a dual phase. The former has already worked as a 300 ton unit (ICARUS) but more R&D is needed to re ach the desired module size of 10 kton. The later has many benefits in ter ms of signal to noise ratio\, imaging capabilities\, scalability\, and cos t reduction but has not yet been proven on a large scale. The task of WA10 5 is to build ProtoDUNE DP – a large dual phase (DP) demonstrator – an d to test it with charged particle beams (0.5-20 GeV/c) at CERN in 2018. T he data will provide the necessary calibration of the detector and benchma rk reconstruction algorithms. This project is a crucial milestone for DUNE . If successful\, DP is likely to become the second 10 kton module to be i nstalled at SURF.\n\nThe key advantage of DP TPC is the benefit of charge amplification in the gas phase using Large Electron Multipliers (LEM). Ele ctrons produced by energetic charged particles in the active volume of liq uid argon drift along the z-axis towards the top anode and enter the gas l ayer. Here\, a readout plane with LEM tiles provides amplification and cha rge collection yielding equal charge sharing in the x and y direction. PMT s located on the bottom of the tank provide trigger for non-beam events by registering the scintillation light generated by charged particles in liq uid argon.\n\nThe active volume of ProtoDUNE DP will be 6 x 6 x 6 m3 (~300 t of LAr). Both the size and the construction details were chosen to test scalable solutions for the crucial aspects of this detector: ultra-high a rgon purity in a non-evacuable tank\, long drifts\, very high drift voltag es\, large area Charge Readout Plane\, cold preamplifiers\, etc. The TPC w ill be installed inside of a tank based on industrial LNG technology.\n\nh ttps://indico.inp.nsk.su/event/8/contributions/1647/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1647/ END:VEVENT BEGIN:VEVENT SUMMARY:Characterization of GaAs:Cr Timepix hybrid pixel detectors DTSTART;VALUE=DATE-TIME:20170228T100000Z DTEND;VALUE=DATE-TIME:20170228T110000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1648@indico.inp.nsk.su DESCRIPTION:Speakers: Petr Smolyanskiy (JINR)\nHigh resistivity gallium ar senide compensated by chromium fabricated by Tomsk State University has de monstrated a good suitability as sensor material for hybrid pixel detector s used in X-ray imaging systems with photon energies up to 60 keV.

Cs$_2$HfCl$_6$ (CHC)\, in particular\, a crystal belonging to the same structure group\, is one of the most promising scintillator for gamma spectroscopy giving almost 54 000 ph/MeV light yield and 3.3$\\%$ energy resolution at 662 keV. In addit ion\, the CHC crystal is the first scintillating material containing a hig h fraction of Hf in mass (of about 25$\\%$). This opens new opportunities to search for a rare nuclear processes occurring in Hf isotopes applying t he "source = detector" experimental approach with high sensitivity. \n\nHe re we report the results of our investigation into a 3 cm$^{3}$ CHC crysta l as a promising detector of search for rare nuclear processes occurring i n Hf isotopes. For this reason\, the response of the crystal to irradiatio n by alpha particle was studied. The quenching factor for 5 MeV alpha part icles is 0.28\, showing that alpha particles produce almost a third of the light produced by gamma quanta. This crystal has also shown the ability t o discriminate between different types of radiation by applying pulse-shap e discrimination techniques. For example\, using the optimal filter method we determined the separation between signals with a Factor of Merit (FOM) = 6.08 for energy at 1 MeV. This means we can fully separate signals indu ced by alpha particles from those of gamma quanta. Similar results were ob tained using the mean time method. \n\nThe internal radioactive contaminat ion of our 3 cm$^3$ CHC was also studied. Using low-background measurement s with germanium gamma-spectrometer at Gran Sasso Underground Laboratory ( Italy). The resulting analysis concluded that the crystal is free from nuc lides of U/Th natural decay chains\, only limits were set of their activit ies at the level of few mBq/kg were seen after 500 hours of measurements.

Four layers of Si licon sensors\, possibly interleaved with Tungsten\, are foreseen to provi de precision timing information for charged and neutral particles with a t ime resolution of the order of 50 pico-seconds per readout cell in order t o assign the energy deposits in the calorimeter to different proton-proton collision vertices. Each readout cell has a transverse size of only a few mm\, leading to a highly granular detector with several hundred thousand readout cells. Using the information provided by the detector\, the contri bution from pile-up jets can be reduced significantly while preserving hig h efficiency for hard-scatter jets. The expected improvements in performan ce are in particular relevant for physics processes with forward jets\, li ke vector-boson fusion and vector-boson scattering processes\, and for phy sics signatures with large missing transverse energy. Silicon sensor tech nologies under investigation are Low Gain Avalanche Detectors (LGAD)\, pin diodes\, and HV-CMOS sensors. The physics motivations and expected perfor mance of the High Granular Timing Detector at the HL-LHC are summarized. T he proposed detector layout and Front End readout\, laboratory and beam te st characterization of sensors and the results of radiation tests are pres ented.\n\nhttps://indico.inp.nsk.su/event/8/contributions/1658/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1658/ END:VEVENT BEGIN:VEVENT SUMMARY:Radiation Hardness tests with neutron flux on different Silicon ph otomultiplier devices DTSTART;VALUE=DATE-TIME:20170228T100000Z DTEND;VALUE=DATE-TIME:20170228T110000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1659@indico.inp.nsk.su DESCRIPTION:Speakers: paolo walter cattaneo (INFN Pavia)\nRadiation hardne ss is an important requirement for solid state readout elements operating in high radiation environments common in particle physics experiments.

This com bination of parameters determines the main application of these detectors in particle physics experiments: precise tracking in the areas close to th e beam and in the end-cap regions of general purpose detectors. \nMPGDs of different configurations have been developed and are under development fo r several experiments in the Budker INP. The system of 8 two-coordinate de tectors based on cascade of Gas Electron Multipliers (GEM) is working at t he KEDR experiment at the VEPP-4M collider in the tagging system that dete cts electrons and positrons\, lost their energy in two-photon interactions and taken out of the equilibrium orbit by a dedicated magnetic system. \n Another set of cascaded GEM detectors is developed for the almost-real Pho tons Tagging System (PTS) of the DEUTRON facility at the VEPP-3 storage ri ng. The PTS contains 3 very light detectors (material content is about 0. 2% of radiation length) with very high spatial resolution (below 50 um). A t present the system is completed and the detectors are under tests at the extracted electron beam facility at the VEPP-4M collider. \nDedicated det ectors based on cascaded GEMs are developed for the extracted electron bea m facility at the VEPP-4M collider. These devices will allow precise parti cle tracking with minimal multiple scattering having very low material con tent (about 0.2% of radiation length). The readout structure of these dete ctors has 0.25 mm strip pitch in X and Y directions\, and spatial resoluti on below 50 um is expected from them according to the simulation studies. The last results from the first detector of this series will be presented at the Conference.\nAn upgrade of the coordinate system of the CMD-3 detec tor at the VEPP-2000 collider is proposed on the basis of the resistive mi cro-WELL (mu-rWELL). This structure is in fact the GEM lying at the resist ive surface that have readout structure below the resistive layer. If a hi gh voltage is applied between the top GEM electrode and the resistive laye r\, the gas amplification occurs in the GEM holes (wells) and such structu re works as a surface with distributed amplification. An advantage of such approach in comparison with cascaded GEMs system is that there is only on e active surface and\, thus\, a detector with curved (i.e. cylindrical) su rface can be easier to manufacture. We propose to make a thin cylindrical chamber based on mu-rWELL and thin end-cap disc detectors based on the sam e technology.

The primary goal of LHCb experiment is the search for indirect evidence of new physics in CP violation and rare d ecays of hadrons\, which contain heavy quarks.\n The calorimeter system of LHCb consists of four sub-detectors: Scintillator Pad Detector followe d by a Preshower detector and then an electromagnetic (ECAL) and hadronic (HCAL) calorimeters. The main purpose of the calorimeter system is the ide ntification of hadrons\, photons and electrons\, and the measurement their energies and positions. This information is the basis of the Level-$0~$ t rigger\, which is required for initial event selection.\n The LHCb ECAL is a «shashlik» type calorimeter of $25$ $X_{0}$ thickness. A number of calibration techniques are applied sequentially. The final calibration me thod is based on reconstruction of the $\\pi^{0}$ meson invariant mass\, w hich allows to achieve the accuracy of measuring the electron and photon e nergies of $2\\%$.\n The Hadron Calorimeter is a sampling iron-scintill ator calorimeter of $5.6~$ nuclear interaction lengths thickness with stru cture arranged along the collider beam direction. HCAL calibration is base d on hydraulic movement of ∼ $10$ mCi radioactive ${}^{137}Cs~$ source through every cell. This method provides very detailed information about t he calorimeter and allows to measure the response of every individual scin tillating tile.\nThe layout of the LHCb calorimeters and these calibration systems and details of the calibration procedures are reported.

Coordinate of an electron (or positron) in a focus sing magnetic spectrometer built in a circular accelerator depends on its energy $E$\, spectrometer parameters $A$\, $B$\, and circulating beam ener gy $E_0$: $X = A E_0 / E + B$. To define parameter $A$\, Compton backscatt ering with two wavelengths can be applied\, which produces two scattered e lectron energies strictly coupled with the beam energy. Parameter $B$ is d efined using coordinate detector for Compton backscattered photons. This d etector should be calibrated in the coordinate frame of the spectrometer e lectron detector using precisely measured beam energy or precision geometr y measurements. Thus\, the beam energy can be defined with expected uncert ainty better than $10^{-4}$.\nBuilt-in focussing magnetic spectrometer is an essential part of VEPP-4M collider\, it is intended for two-photon proc esses study at KEDR detector. It has Compton calibration system with two l asers. Also photons scattered from interaction point can be registered by coordinate detector. Thus\, the the technique proposed could be implemente d here with minimum efforts\, test of the technique is planned with the pr esent equipment. To measure VEPP-4M beam energy in whole energy range 1.5- 5.0 GeV (which is essential for future precision experiments at KEDR detec tor in $\\Upsilon$ mesons energy range) the installation needs an extra eq uipment and optimisation\, they are also planned after the test.\n\nhttps: //indico.inp.nsk.su/event/8/contributions/1680/ LOCATION:Budker Institute of Nuclear Physics URL:https://indico.inp.nsk.su/event/8/contributions/1680/ END:VEVENT BEGIN:VEVENT SUMMARY:Luminosity measurements at LHCb DTSTART;VALUE=DATE-TIME:20170227T081000Z DTEND;VALUE=DATE-TIME:20170227T083000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1681@indico.inp.nsk.su DESCRIPTION:Speakers: Vladislav Balagura (CNRS / LLR - Ecole polytechnique )\nLuminosity measurements at LHCb are of pivotal importance.\nThey have b een used in about 50 LHCb publications of production cross section results .\nThe interaction rate at LHCb is continuously monitored by several lumi nosity counters\n(like the number of reconstructed tracks) measuring the f raction of "empty" events\,\ni.e. events which fall below a chosen thresho ld of a given luminosity counter.\nUsing the law of Poisson statistics\, a n average interaction rate per bunch crossing\nis derived from the "empty" events fraction.\nThe absolute calibration of the luminosity counters is performed a few times per year\n(typically for each new beam energy and be am types)\, mostly in dedicated LHC fills.\nTwo techniques are employed fo r the direct luminosity measurement.\nThe first one is the classic van der Meer scan method which is used by all four LHC\nexperiments. The second o ne is unique to LHCb. Here\, the beam\nprofiles and their overlap integral are determined from the\nbeam "images" recorded with beam-gas interaction s.

This TPC is the largest TPC built so far (almost $90\\te xtrm{m}^3$ volume) and - while operated in a 0.5T magnetic field - provide s a momentum resolution of $\\textrm{d}p/p=1\\%$ (at the multiple scatteri ng limit) as well as a $\\textrm{d}E/\\textrm{dx}$ resolution of $5$-$7\\% $. The readout chambers are Multi Wire Proportional Chambers (MWPCs)\, emp loying a gating grid to prevent ions\, which are produced during the gas a mplification\, from moving into the drift volume. Hence there is a maximal readout rate of about 3kHz - given by the closing time of the grid ($\\si m 250\\textrm{ms}$) and the electron drift time through the whole TPC ($\\ sim 90\\textrm{ms}$).\n\nAfter the long shut-down 2 (from 2021 onwards) th e LHC will provide lead-lead collisions at interaction rates of 50kHz. In order to cope with these rates the TPC needs to be upgraded with new reado ut chambers\, which allow for continuous read-out and preserve the energy and momentum resolution of the current MWPCs. Therefore the amount of ions in the drift volume can only be as big as $1\\%$ of the ions produced dur ing the gas amplification. Hence the ion back flow from the chambers has t o be small. It was found that chambers with a stack of four Gas Electron M ultipliers (GEMs) fulfil these requirements\, if the voltages applied to a ll the GEMs are tuned properly. In addition the chambers must be stable wh ile being operated at the LHC. Hence studies of the discharge behaviour wi th small prototypes (equipped with only one or two GEMs) as well as stabil ity studies with full readout chambers have been performed. During these s tudies the phenomenon of "secondary discharges" was observed. This special kind of discharge occurs after an initial discharge in a time between 0 t o several $10\\textrm{ms}$\, if the electric field above or below the GEM is high enough.\n\nIn this talk we will give an overview of the ALICE TPC upgrade and of the current design status of the GEM based readout chambers . We will focus on the studies of the chamber stability and present our cu rrent knowledge on the observed "secondary discharges" and our measures on how to avoid them. This includes our considerations of the high voltage s upply schema. In addition we'll give a short outlook on the challenges of the mass production of the new readout chambers.\n\nhttps://indico.inp.nsk .su/event/8/contributions/1683/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1683/ END:VEVENT BEGIN:VEVENT SUMMARY:The micro-RWELL detector DTSTART;VALUE=DATE-TIME:20170302T041000Z DTEND;VALUE=DATE-TIME:20170302T043000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1684@indico.inp.nsk.su DESCRIPTION:Speakers: Giovanni Bencivenni (LNF - INFN)\nThe R&D on the mic ro-Resistive-WELL (μ-RWELL) detector technology aims in developing a new scalable\, compact\, spark-protected\, single amplification stage Micro-Pa ttern Gas Detectors (MPGD) for large area HEP applications as tracking and calorimeter device as well as for industrial and medical applications as X-ray and neutron imaging gas pixel detector.

The weak equivalent principle (WEP) can be tested measuring the gravitat ional acceleration of antihydrogen atoms in the Earth's gravitational fiel d that are\nhorizontally emitted from a Penning trap. The antihydrogen ato ms can be produced via resonant charge exchange of Rydberg positronium and antiprotons at temperatures potentially determined by the recoil limit of the constituents. To prepare an ensemble of cold antihydrogen with a narr ow velocity spread we plan to extend the existing electron cooling mechani sm of antiprotons by laser-cooling techniques of negative C2- molecules in a Penning trap in order to sympathetically cool antiprotons to the mK reg ime. The generation of cold antihydrogen atoms can ultimately also be used for precision spectroscopy experiments of electromagnetic interaction as a test of CPT symmetry. In this presentation the status of the experiment at CERN and the feasibility of sympathetic cooling of antiprotons using ph oto-detachment and AC Stark Sisyphus cooling of C2- will be reviewed.\n\nh ttps://indico.inp.nsk.su/event/8/contributions/1693/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1693/ END:VEVENT BEGIN:VEVENT SUMMARY:The Belle II Software - From Detector Signals to Physics Results DTSTART;VALUE=DATE-TIME:20170227T110500Z DTEND;VALUE=DATE-TIME:20170227T113000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1694@indico.inp.nsk.su DESCRIPTION:Speakers: Thomas Kuhr (LMU)\nhttps://indico.inp.nsk.su/event/8 /contributions/1694/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1694/ END:VEVENT BEGIN:VEVENT SUMMARY:Development of ATLAS Liquid Argon Calorimeter Readout Electronics for the HL-LHC DTSTART;VALUE=DATE-TIME:20170301T041500Z DTEND;VALUE=DATE-TIME:20170301T043500Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1698@indico.inp.nsk.su DESCRIPTION:Speakers: Gustaaf Brooijmans (Columbia University)\nThe LHC hi gh-luminosity upgrade in 2024-2026 requires the associated detectors to op erate at luminosities about 5-7 times larger than assumed in their origina l design. The pile-up is expected to increase to up to 200 events per prot on bunch-crossing. To be able to retain interesting physics events even at rather low transverse energy scales\, increased trigger rates are foresee n for the ATLAS detector. At the hardware selection stage acceptance rates of 1 MHz are planned\, combined with longer latencies up to 60 micro-seco nds in order to read out the necessary data from all detector channels. Un der these conditions\, the current readout of the ATLAS Liquid Argon (LAr) Calorimeters does not provide sufficient buffering and bandwidth capabili ties. Furthermore\, the expected total radiation doses are beyond the qual ification range of the current front-end electronics. For these reasons a replacement of the LAr front-end and back-end readout system is foreseen f or all 182\,500 readout channels\, with the exception of the cold pre-ampl ifier and summing devices of the hadronic LAr Calorimeter. The new low-pow er electronics must be able to capture the triangular detector pulses of a bout 400-600 nano-seconds length with signal currents up to 10 mA and a dy namic range of 16 bit. Different technologies to meet these requirements a re under evaluation:\nA preamplifier in 130nm CMOS technology with two gai n stages can cover the desired dynamic range while meeting the required no ise levels and non-linearity values. Alternatively\, developments of pre-a mplifier\, shaper as well as ADCs are performed in 65 nm CMOS technology. Due to the lower voltage range\, 2-gain and 4-gain designs of the analog p art are studied with programmable peaking time to optimize the noise level in presence of signal pile-up. Radiation-hard\, 14 bit ADC operating at 4 0 or 80 MHz are also being studied. Results from performance-simulation of the calorimeter readout system for the different options and results from design studies and first tests of the components will be presented.\n\nht tps://indico.inp.nsk.su/event/8/contributions/1698/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1698/ END:VEVENT BEGIN:VEVENT SUMMARY:Silicon micro-strip detector for imaging of fast processes at high intensity synchrotron radiation beam DTSTART;VALUE=DATE-TIME:20170228T100000Z DTEND;VALUE=DATE-TIME:20170228T110000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1699@indico.inp.nsk.su DESCRIPTION:Speakers: Lev Shekhtman (Budker Institute of Nuclear Physics)\ nThe technique of imaging of fast processes at high intensity synchrotron radiation (SR) beam is developed in the Budker Institute of Nuclear Physic s since the beginning of 2000s. The DIMEX (Detector for Imaging of Explosi ons) based on gas ionization chamber is working at the channel 0 at the VE PP-3 storage ring and at the channel 8 at the VEPP-4M storage ring. Howeve r\, the gaseous detector can not provide the necessary parameters for the experiments at the channel 8 at the VEPP-4M\, where photon flux is up to 1 00 times higher than at the channel 0 at the VEPP-3. In particular the rat e capability of gaseous detector is far not enough due to the space charge effects induced by slow positive ions. The Si micro-strip detector is pro posed for high rate experiments at the VEPP-4M storage ring. The first S i sensors were produced by Hamamatsu Photonics and included 1024 p-strips on n substrate with DC metal strips. The strip pitch is 50 $\\mu$m and the strips length is 30 mm. Each metal strip is connected to the guard ring t hrough ~400 Ohm polysilicon resistor in order to drain high current from t he sensor to ground. The front-end electronics will measure the voltage dr op on such resistor. A dedicated ASIC is developed for this detector that is able to measure signals from each strip in the range equivalent to 1000 to 10$^6$ photons with 30 keV energy and store them in the analogue memor y with the frame rate up to 50 MHz. The first prototype of such detector t hat will include 120 channels equipped with the prototype ASICs is assembl ed now and the first results of the measurements will be shown in the pres entation.\n\nhttps://indico.inp.nsk.su/event/8/contributions/1699/ LOCATION:Budker Institute of Nuclear Physics URL:https://indico.inp.nsk.su/event/8/contributions/1699/ END:VEVENT BEGIN:VEVENT SUMMARY:Development of a silicon micro-strip detector with single photon s ensitivity for fast dynamic diffraction experiments at a synchrotron radia tion beam.

SR channel 8 of the VEPP-4M storage ring provides radiation from the 7-pole wiggler that allows to get up to several tens photons within 1 $\\mu$s from a W crys tal for the most intensive diffraction peak. In order to perform experimen ts that allow to measure the evolution of W crystalline structure under th e impact of powerful laser beam\, a new detector is developed\, that can p rovide information about the distribution of scattered SR flux in space an d its evolution in time at a microsecond scale. The detector based on the silicon p-on-n micro-strip sensor with DC metal strips. The sensor contai ns 1024 30 mm long strips with 50 micron pitch. 64 strips are bonded to th e front-end electronics based on APC128 ASICs.

TileCal is a sampling calorimeter with stee l as absorber and scintillators as active medium. The scintillators are re ad-out by wavelength shifting fibers coupled to photomultiplier tubes (PMT ). The analogue signals from the PMTs are amplified\, shaped and digitized by sampling the signal every 25 ns.\n\nThe High Luminosity Large Hadron C ollider (HL-LHC) will have a peak luminosity of 5x10$^{34}$cm$^{-2}$s$^{-1 }$\, five times higher than the design luminosity of the LHC.\nTileCal wil l undergo a major replacement of its on- and off-detector electronics for the high luminosity programme of the LHC starting in 2026. All signals wil l be digitized and then transferred directly to the off-detector electroni cs\, where the signals will be reconstructed\, stored\, and sent to the fi rst level of trigger at a rate of 40 MHz. This will provide better precisi on of the calorimeter signals used by the trigger system and will allow th e development of more complex trigger algorithms. Changes to the electroni cs will also contribute to the reliability and redundancy of the system.\n \nThree different frontend options are presently being investigated for th e upgrade and a final solution will be chosen after extensive laboratory a nd test beam studies that are in progress. A hybrid demonstrator module wa s developed using the new electronics while conserving compatibility with the current system.

Jointly with othe r calorimeters it is designed for energy reconstruction of hadrons\, jets\ , tau-particles and missing transverse energy. The scintillation light pro duced in the scintillator tiles is transmitted by wavelength shifting fibe rs to photomultiplier tubes (PMTs). The analog signals from the PMTs are a mplified\, shaped and digitized by sampling the signal every 25 ns. The Ti leCal frontend electronics reads out the signals produced by about 10000 c hannels measuring energies ranging from ~30 MeV to ~2 TeV. Each stage of t he signal production from scintillation light to the signal reconstruction is monitored and calibrated.\n\nThe performance of the calorimeter has be en established with cosmic ray muons and the large sample of the proton-pr oton collisions.

Herewith\, one of the main objectives\, appearing during EAS registration\, is primary p article identification. EAS\, produced by proton or nucleus\, content 30-5 0 times more muons than EAS\, produced by gamma-quanta with the same energ y. This way\, muon component of shower registration can give extra informa tion about primary particle. Muon registration is performed by scintillati on detectors. Within the TAIGA experiment (Tunka Advanced Instrument for c osmic-ray physics and Gamma Astronomy)\, it is suggested to construct the EAS’s muon component registration system on the area of about 5 sq.km. M uon system must include two layers of detectors\, which will be placed on a surface and underground for separation of the muon component of a shower . The total detection area must cover more than 0.1% of the total area of the observatory. That means that one of the main requirements to the devel oped detector is a low cost. The design of a scintillation counter with wa velength shifters was developed. The use of wavelength shifters for collec tion of a scintillation light allows using of PMT’s with small photocath ode diameter\, that decreases counter’s price. For technology verificati on\, counter prototype with scintillator area of 0.25 sq.m.\, was created. Prototype was successfully tested with nature muon background\, what prov ed applicability of chosen design. At present\, assembly of a counter with scintillator area of 1 sq.m\, placed in sealed container made from stainl ess steel\, is in progress.\n\nhttps://indico.inp.nsk.su/event/8/contribut ions/1724/ LOCATION:Budker Institute of Nuclear Physics URL:https://indico.inp.nsk.su/event/8/contributions/1724/ END:VEVENT BEGIN:VEVENT SUMMARY:The 32-channel TDC based on Altera Cyclone III FPGA.

The low-thermal gradi ent Chozchralski (LTG CZ) crystal growth technique provide excellent quali ty large volume crystal scintillators thanks to absence of thermoelastic s tress in the crystal and overheating of the melt. The features are particu larly significant in production of crystalline materials with strong therm al anisotropy properties and low mechanical strength. Another advantage of the LTG CZ method is a much lower level of the melt evaporation. It allow s to improve the melt stoichiometry and minimize losses of the charge\, cr ucially important in production of crystal scintillators from enriched iso topes. The LTG CZ is especially efficient in large volume scintillators pr oduction. Radiation-resistant high optical properties bismuth germanate cr ystals with mass up to 75 kg were produced for high energy physics and ast rophysical experiments. Production of high performance cadmium tungstate c rystals with mass 20 kg is well established too. The LTG CZ technique look s an out-of-competition approach to produce crystal scintillators from enr iched isotopes for double beta decay experiments. Excellent quality cadmiu m tungstate crystal scintillators from enriched 106Cd and 116Cd with a yie ld of crystal boule up to 85% of initial charge\, and very low irrecoverab le losses less than 1%\, were obtained. Similar specifications were also a chieved in R&D of zinc and lithium molybdenum crystals from enriched 100Mo for cryogenic double beta experiments. It should be stressed that the LTG CZ method opens a possibility to obtain deeply radiopure crystal scintill ators by using double crystallization with reasonable amount of starting m aterial thanks to the very large yield of crystalline boules. An R&D is in progress to produce highly radiopure zinc tungstate crystal scintillators for the ADAMO dark matter project aiming at search for the directionality of Dark Matter candidate particles.

The con version process results in a monochromatic electron with an energy slightl y below the muon rest mass (104.97 MeV). Goal of the experiment is to impr ove of four orders of magnitude the previous measurement with similar tech nique and reach a single event sensitivity of 2.5 x 10$^{-17}$ on the conv ersion rate with respect to the muon capture rate. \n\nAlthough the SM is very well tested in many regimes\, it appears likely to be incomplete. In many of the Beyond the Standard Model (BSM) scenarios\, rates for CLFV pr ocesses are within the reach of the next generation of experiments. In par ticular\, if SUSY particles have masses and couplings within the discover y reach of the LHC\, CLFV rates will be observable. On the contrary\, many CLFV searches have a sensitivity to new physics that exceeds the LHC reac h bringing the reach of new mass scale up to $10^4$ TeV. In this contest i ndirected measurements of CLFV will be crucial evidence of new physics. Co mplementarity of Mu2e and MEG upgrade is relevant in this respect.\n\nThe experiment goal is obtained with a very intense (20 GHz) pulsed negative muon beam sent to an Aluminium target for a total number of 10^{18} stoppe d muons in three years of running. Production and transport of the muons i s done with a complicated and sophisticated magnetic systems composed by a production\, a transport and a detector solenoid. The magnetic systems al lows to bring this very intense beam to target with a low request on powe r. Description and status of the magnetic system will be reported. \n\nThe improvement with respect to previous conversion experiments is based on f our elements: the muon intensity\, the beam structure layout\, the extinct ion of out of time particles and the precise electron identification in th e detector solenoid. The conversion electron will be reconstructed and sep arated by the Decay in Orbit (DIO) background by a very high resolution (1 20 keV) tracking system based on straw technology. The crystal calorimeter system will confirm that the candidates are indeed electrons by performin g a powerful mu/e rejection while granting a tracking independent HLT filt er.

Physikalisches Institut B\, RWTH Aachen)\nThe CMS experiment features as its innermost component a silicon pixel detector which provides high precision space point measurements of charged particle trajectories. The original detector was designed for an i nstantaneous luminosity of $1.0 x 10^{34} cm^{-2} s^{-1}$. Due to improvem ents of the LHC this luminosity was already exceeded in 2016 and it is for eseen that it will be further increased up to two times the design value b efore 2018. This will lead to more interactions per bunch crossing and als o the inefficiencies caused by the readout electronics will rise.\n\nTo ma intain the excellent tracking efficiency\, the CMS collaboration has built a new pixel detector with the plan to install it in an extended technical shutdown at the beginning of 2017. The Phase I pixel detector features an additional fourth layer in the barrel part and an additional third layer in the endcaps. The material budget could still be reduced by a lightweigh t carbon fiber support structure and a new cooling system using a two-phas e CO2 cooling. To reduce data losses\, new readout chips with larger buffe rs and a digital readout have been developed and the readout electronics w as upgraded. Furthermore the new detector features a novel powering scheme using DC-DC converters.\n\nThis contribution will motivate the design cho ices for the new pixel detector and their impact on the tracking performan ce. With a special focus on the barrel detector\, the production and quali fication of pixel modules and the power system components will be discusse d and final results will be presented. The results of system tests that we re carried out with the DC-DC power system will be shown. The status of th e mounting of components onto the support structures\, the associated test procedures including results\, and the status of the installation of the whole detector into CMS will be discussed.\n\nhttps://indico.inp.nsk.su/ev ent/8/contributions/1736/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1736/ END:VEVENT BEGIN:VEVENT SUMMARY:Optimization of the beam crossing angle at the ILC for e+e- and g amma-gamma collisons DTSTART;VALUE=DATE-TIME:20170227T094000Z DTEND;VALUE=DATE-TIME:20170227T100000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1737@indico.inp.nsk.su DESCRIPTION:Speakers: Valery Telnov (BINP\, Novosibirsk Univ.)\nIn the pre sent ILC design the beam crossing angle for e+e- collisions is 14 mrad.

The key to the GEM application at large-scale experiments is cost-effective realization of large-size detectors\, in whi ch development of GEM detector assembly techniques plays a key role. The d etector group at the University of Science and Technology of China (USTC) has been conducting intensive R&D on large-size GEM detectors\, particular ly on assembly techniques of GEM detectors\, since 2013. The main aim is t o build up technology for constructing the tracking detector at the SoLID experiment proposed for the 12-GeV upgrade program at JLab.\n\nWe started large-size GEM R&D by implementing the self-stretching GEM assembly techni que developed at CERN for the CMS Muon GEM upgrade project\, and gained a great deal of experience with the self-stretching technique through large- size GEM detector prototyping. \n\nFrom our implementation and practice of the self-stretching technique\, we found a major disadvantage of the tech nique in application for very large GEM detectors with size larger than 1m . When GEM foil size reaches over 1m\, the overall foil extension of a tri ple-GEM under tension of ~ 5N/cm can be as large as ~2.5mm. This was preci sely measured by a dedicated GEM stretching test station. The screws used to stretch foils would then be pulled by the inner frames and tilted towar ds the GEM stretching direction\, and finally exceed the tolerance of the screw hole size and get blocked. This would result in partial application of stretching force to the foils and improper setting of O rings in the sc rew holes which could further cause gas leakage. In view of these problems \, we have developed a new GEM stretching technique called “sliding self -stretching” based upon the original self-stretching technique. In this new technique\, the nuts are fixed by the main frame which forces the stre tching screws to keep vertical to the side-plane of the mainframe\, and th e GEM foils can move freely up to 5mm with respect to the main frame. With this sliding self-stretching technique\, GEM foils as large as ~1m can st ill be stretched very uniformly while gas tightness is ensured. A large-s ize GEM prototype (1m×0.5m) has been successfully built with this new tec hnique\, demonstrating the advantage of the sliding self-stretching techni que over the original one in large-size GEM assembly. The GEM prototype wa s thoroughly tested in terms of uniformity and effective gain. In order to test the spatial resolution of the prototype\, we have built a GEM readou t system based on APV25. As the first step\, we tested a 30 cm×30 cm GEM detector with the readout system\, and obtained a good result.\n\nThis rep ort presents the details of the sliding self-stretching technique for larg e-size GEM assembly and test results of a large-size GEM prototypes built with the technique. The performance of the GEM prototypes is also compare d to that of large-size GEM detectors built with other techniques.\n\nhttp s://indico.inp.nsk.su/event/8/contributions/1738/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1738/ END:VEVENT BEGIN:VEVENT SUMMARY:A new Scintillating Fibre Tracker for LHCb experiment DTSTART;VALUE=DATE-TIME:20170228T092000Z DTEND;VALUE=DATE-TIME:20170228T094000Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1747@indico.inp.nsk.su DESCRIPTION:Speakers: Alexander Malinin (NRC "Kurchatov Institute")\nThe L HCb detector will be upgraded during the Long Shutdown 2 (LS2) of the LHC in order to cope with higher luminosities and to read out the data at 40MH z using a trigger-less read-out system.

The neutron-antine utron pair production events can be detected only by the calorimeters. In the barrel calorimeter the antineutron annihilation typically occurs about 5 ns or later after the beams crossing. For identification of such events it is necessary to measure the time of flight of particles to the LXe-cal orimeter with an accuracy of about a few nanoseconds. The LXe-calorimeter consists of 14 layers of ionization chambers with two readout: anode and c athode. The duration of charge collection to the anodes is about 4.5 µs\, while the required accuracy of measuring of the signal arrival time is le ss than 1/1000 of that (i.e. 4.5 ns). Besides\, the signals’ shapes diff er substantially from event to event\, so the signal arrival time is measu red in two stages.

However\, these devices are sensitive to radiation effects such as single event upsets (SEUs) or multiple bit upsets (MBUs) i n the configuration memory\, which may alter the functionality of the impl emented circuit. Therefore\, they are normally employed only in off-dete ctor regions\, where no radiation is present. Special families of SRAM-ba sed FPGAs (e.g. the Xilinx Virtex-5QV) have been designed for applications in radiation environments\, but their excessive cost (few 10k USD)\, with respect to their standard counterpart ($\\sim$ 500 USD)\, usually forbids their usage in many applications\, including HEP. Therefore\, there is a strong interest in finding solutions for enabling the usage of standard SR AM-based FPGAs also on-detector. Methods based on modular redundancy and periodic refresh of the configuration\, i.e. configuration scrubbing\, are used in order to mitigate single event effects\, which become more signif icant as the technological scaling proceeds towards smaller feature sizes. In fact\, latest devices also include dedicated circuitry implementing er ror correcting codes for mitigating configuration errors. The expected bit configuration upset rate is valuable information for choosing which prote ction strategy\, or which mixture of strategies\, to adopt. \nTypically\, test campaigns are carried out at dedicated irradiation facilities by mean s of heavy ions\, proton and neutron beams [3\,4\,5] and they permit to de termine the particle to bit error cross section. However\, a reliable pred iction of the upset rate\, and of radiation effects in general\, requires the knowledge of the cross section as function of the particle species and their spectra and it depends on a detailed knowledge of the radiation flu xes. Often such information is not available with sufficient precision\, a nd when possible an in situ (or in flight for space applications) measurem ent of the upset rate is highly recommended. For instance\, experiments at the Large Hadron Collider have been monitoring SEUs in readout control FP GAs [6]\, experiments in space have been launched in order to measure sing le event effects rates and compare them to predictions based on cross sect ions [7]. Furthermore\, over the last decade\, FPGA vendors have been carr ying out experiments aimed at measuring SEUs induced by atmospheric neutr ons in their devices [8].\n\nIn February 2016\, the SuperKEKB [9] $e^+e^-$ high-luminosity ($8\\cdot10^{35} cm^{-2} s^{-1}$) collider of the KEK lab oratory (Tsukuba\, Japan) started being commissioned. A dedicated commissi oning detector\, named BEAST2\, has been being used to characterize beam b ackgrounds prior to the Belle2 detector roll into the beams and to provide tuning parameters for Monte Carlo simulations. BEAST2 consists of a fiber glass support structure and several subdetectors mounted onto it\, includ ing time projection chambers (TPCs) and He-3 tubes. \n\nIn this work\, we present direct measurements of radiation-induced soft-errors on a SRAM-bas ed FPGA device installed on the BEAST2 frame at a distance of $\\sim$ 1 m from the beam interaction point. Our goal is to provide experimental resul ts of the expected FPGA configuration error rate and power consumption var iation at Belle2 and at other experiments operating in similar radiation c onditions. For this study\, we designed a dedicated board hosting a Xilin x Kintex-7 325T device without additional active components\, in such a w ay to be able to decouple FPGA failures from those of other devices. The b oard receives power and clock from dedicated remote generators installed i n a counting room. The configuration and read back are performed via a JTA G connection and they are managed by a dedicated single board computer . D uring the commissioning of the collider\, we periodically read back the FP GA configuration in order to detect errors and we logged the power consump tion on the different power domains of the device. Currents for both elect ron and positron rings spanned a range between 50 and 500 mA\, therefore p roviding data about the FPGA in different radiation conditions. Even if th e machine is not providing collisions yet\, as the beams are not focused t o the interaction point\, our results show a rate of 0.02 upsets/day avera ged over the whole commissioning time frame. BEAST2 subdetectors provided valuable information about the radiation environment.\nThis work is part o f the ROAL SIR project funded by the Italian Ministry of Research (MIUR).\ n\n\nReferences \n\n[1] Xilinx Inc.\, “Virtex UltraScale FPGAs Data Shee t: DC and AC Switching Characteristics\,” DS893 (v1.7.1) April 4\, 2016\ n\n[2] Altera Corp.\, “Stratix 10 Device Overview\,” S10-OVERVIEW\, 2 015.12.04\n\n[3] D.

Since the current ATLAS trigger system does not allow sufficient incre ase of the trigger rate\, an improvement of the trigger system is required . The Liquid Argon (LAr) Calorimeter read-out will therefore be modified t o use digital trigger signals with a higher spatial granularity in order t o improve the identification efficiencies of electrons\, photons\, tau\, j ets and missing energy\, at high background rejection rates at the Level-1 trigger. The new trigger signals will be arranged in 34000 so-called Supe r Cells which achieves 5-10 times better granularity than the trigger towe rs currently used and allows an improved background rejection. The readout of the trigger signals will process the signal of the Super Cells at ever y LHC bunch-crossing at 12-bit precision and a frequency of 40 MHz. The d ata will be transmitted to the back-end using a custom serializer and opti cal converter and 5.44 Gb/s optical links. In order to verify the full fun ctionality of the future Liquid Argon trigger system\, a demonstrator set- up has been installed on the ATLAS detector and is operated in parallel to the regular ATLAS data taking during the LHC Run-2. Noise level and linea rity on the energy measurement have been verified to be within our require ments.

The lead tungstate (PbWO4) crystals forming the ba rrel part of the Electromagnetic Calorimeter (ECAL) of the Compact Muon So lenoid (CMS) will still perform well\, even after the expected integrated luminosity of 3000fb-1 at the end of HL-LHC. The avalanche photodiodes (AP Ds) used to detect the scintillation light will also continue to be operat ional\, although there will be some increase in electronics noise due to r adiation-induced APD dark currents.\n\nDuring the third long shutdown of t he LHC (LS3)\, the barrel ECAL will undergo extensive changes in order to prepare for the next decade of operation under the more challenging condit ions of the HL-LHC. The barrel operating temperature will be reduced\, to mitigate the increasing APD-induced noise. The most significant change wil l be the replacement of a majority of the on-detector and off-detector rea dout. This will remove existing constraints on trigger rate and latency\, and will provide additional functionality to exploit the higher luminosity delivered by the HL-LHC.\n\nWe start with the comparison of the legacy de tector design goals and the real detector performance. Then we review the design and R&D studies for the barrel calorimeter upgrade and present resu lts from test beam studies of the first prototype readout electronics. We present test beam results on hadron irradiated PbWO4 crystals up to fluenc es expected at HL-LHC and detail the status of the new readout and trigger electronics R&D. The mitigation of the larger number of concurrent intera ctions per bunch crossing (pileup) expected at HL-LHC may be substantially improved by means of precision time tagging of calorimeter clusters\, by associating them to primary vertices via 4D triangulation. We present rece nt test beam results on the precision timing potential of the CMS lead tun gstate calorimeter and discuss how the readout electronics may be adapted to exploit this performance in CMS.\n\nhttps://indico.inp.nsk.su/event/8/c ontributions/1751/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1751/ END:VEVENT BEGIN:VEVENT SUMMARY:Central Tracking for experiment BM&N based on double side silicon detectors.

The possibility to distinguish neutral particles coming from different interaction vertices is being pursued as a tool to reduce pile-up contamin ation in calorimeters\, and restore optimal performance. At the high lumin osity LHC (HL-LHC) about 200 concurrent interactions are expected\, with a spread between the interaction vertices of few centimeters in the beam di rection and 200ps in the collision time. A time of flight resolution of th e order of 30 ps would be able to reduce neutral particles pile-up contami nation at the calorimeter level of about one order of magnitude\, restorin g pile-up conditions similar to what is routinely sustained in the current run of the LHC. Micro-channel plates have been used in PMT configuration as fast charged particles detector (resolution of better than 20 ps have b een achieved with commercial devices)\, however they are not particularly radiation tolerant\, mostly due to the ion feedback on the photocathode. T he possibility of using micro-channel plates without a photocathode (i-MCP ) has been studied in several test beams. Different MCP geometries are com pared with the goal to identify the optimal configuration. Efficiency of m ore then 70% with a time resolution of better than 40 ps are achieved for single charged particles\, leading to an efficiency close to 100% for EM s hower after few radiation lengths. This open the possibility to use i-MCPs as a timing layer in a sampling calorimeter or to use it in a pre-shower device independent from the calorimeter technology.\n\nhttps://indico.inp. nsk.su/event/8/contributions/1753/ LOCATION: URL:https://indico.inp.nsk.su/event/8/contributions/1753/ END:VEVENT BEGIN:VEVENT SUMMARY:Limits of Scintillation Materials For Future Experiments at High L uminosity LHC and FCC DTSTART;VALUE=DATE-TIME:20170301T020000Z DTEND;VALUE=DATE-TIME:20170301T022500Z DTSTAMP;VALUE=DATE-TIME:20260411T052745Z UID:indico-contribution-8-1763@indico.inp.nsk.su DESCRIPTION:Speakers: Mikhail Korjik (INP BSU)\nThis report gives of a rev iew the last results of the radiation damage effects in scintillation mate rials used in high energy physics experiments\, that are caused by γ-quan ta and high energy hadrons\, and neutrons the three main causes of irradia tion in the High Luminosity LHC and future FCC.

The experiment is taking d ata at the e$^{+}$e$^{-}$ collider BEPCII in Beijing (China) and the GEM t racker will be installed in 2018. \nTests on the performances of triple GE Ms in strong magnetic field have been run by means of the muon beam availa ble in the H4 line of SPS (CERN) with both planar chambers and the first c ylindrical prototype. Efficiencies and resolutions have been evaluated usi ng different gains\, gas mixtures\, with and without magnetic field.\nThe obtained efficiency is larger than 95%\, in many operational arrangements. \nThe spatial resolution for planar GEMs has been evaluated with two dif ferent algorithms for the position determination: the charge centroid and the micro time projection chamber (TPC) methods. The two modes are complem entary and are able to cope with the asymmetry of the electron avalanche w hen running in magnetic field\, and with non-orthogonal incident tracks. \ nWith the charge centroid\, a resolution lower than 100 microns has been r eached without magnetic field and lower than 200 microns with a magnetic f ield up to 1 T.
