We propos e a versatile approach to this task that is based on machine learning and can substitute the most computationally intensive steps of the process whi le retaining the GEANT4 accuracy to details. The approach covers entire de tector representation from the event generation to the evaluation of the p hysics performance. The approach allows the use of arbitrary modules arran gement\, different signal and background conditions\, tunable reconstructi on algorithms\, and desired physics performance metrics. Being combined wi th properties of detector and electronics prototypes obtained from beam te sts\, the approach becomes even more versatile. We focus on the Phase 2 Up grade of the LHCb Calorimeter under the requirements on operation at high luminosity. We discuss the general design of the approach\, and particular estimations including occupancies and spatial resolution for the future L HCb Calorimeter setup at different pile-up conditions.\n\nhttps://indico.i np.nsk.su/event/20/contributions/783/ LOCATION:Budker Institute of Nuclear Physics URL:https://indico.inp.nsk.su/event/20/contributions/783/ END:VEVENT BEGIN:VEVENT SUMMARY:Current R&D and Future Trends in Silicon Detectors DTSTART;VALUE=DATE-TIME:20200225T020000Z DTEND;VALUE=DATE-TIME:20200225T023000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-786@indico.inp.nsk.su DESCRIPTION:Speakers: Andreas Mussgiller (DESY)\nWith the LHC experiments preparing their upgrades for the High-Luminosity LHC (HL-LHC) there has be en a natural emphasis on the R&D for their future tracking detectors.

The introduction of a resistive layer ( ρ~50÷200 MΩ/square) mitigating the transition from streamer to spark g ives the possibility to achieve large gains (>10^4)\, while affecting the detector performance in terms of rate capability. Different detector layou ts have been studied: the most simple one based on a single-resistive laye r with edge grounding has been designed for low-rate applications (few ten s of kHz/cm2)\; more sophisticated schemes have been studied for high-rate purposes (≥ 10 MHz/cm2).\nThe single-resistive layer scheme\, extensive ly tested and validated\, it is mature for the technology transfer towards the industry working into the rigid and flexible PCB photolithography.\nT he high-rate version of the detector has been developed in the framework o f the phase-2 upgrade of the LHCB muon system\, where strong requirements on the robustness and rate capability are required. \nAn overview of the d ifferent architectures studied for the high-rate version of the detector\, together with their performance measured at the high intensity PiM1 beam of the PSI will be presented. \n\nThe presence of the resistive layer also affects the charge spread on the strips and consequently the spatial reso lution of the detector: the results of a systematic study of the spatial resolution obtained with the charge centroid (CC) method for orthogonal tr acks as a function of the DLC resistivity will be discussed.\nFor non-orth ogonal tracks the spatial resolution with CC method is compared with the p erformance obtained with the micro-TPC mode: a readout approach that explo iting the combined measurement of the ionization clusters time of arrival and the amplitude of the signals on the strips allows a fine estimation of the position of the track for a wide incident angular range. \n\nThe exce llent performance together with the high flexibility of the technology sug gests the use of such a detector as a high space resolution inner tracker in HEP.\n\nhttps://indico.inp.nsk.su/event/20/contributions/790/ LOCATION: URL:https://indico.inp.nsk.su/event/20/contributions/790/ END:VEVENT BEGIN:VEVENT SUMMARY:Review on the R&D activities within the RD51 Collaboration DTSTART;VALUE=DATE-TIME:20200228T020000Z DTEND;VALUE=DATE-TIME:20200228T023000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-795@indico.inp.nsk.su DESCRIPTION:Speakers: Kondo GNANVO (University of Virginia)\nRecent advanc es in photolithography and micro processing techniques have enabled the em ergence of Micro Pattern Gaseous Detectors (MPGDs) such as Gas Electron Mu ltipliers (GEMs) or Micro Mesh Gaseous Structures (Micromegas) and many ot her more recent technologies.

The use of the ALPIDE-based detector design will reduce the material budget to 0.35%$X_0$ per layer for the inner most three layers\, and to 1. 0%$X_0$ per layer for the outer most four layers\, compared to 1.14%$X_0$ per layer in the previous ITS. The readout rate will be improved to 100 kH z for Pb-Pb interactions\, which is the double of the upgrade requirement. In addition\, the radius of the first layer of the ITS will be reduced fr om 39mm to 23mm and the pixel size reduced to $O(30\\mu m)$ x $O(30\\mu m) $. \n\nThe effort in over 10 construction sites has resulted in a fully as sembled and connected detector\, which is currently under going on surface commissioning before it will be installed in the ALICE cavern in July 202 0. This contribution will discuss the current status of the commissioning of the new ITS\, including the methods used to characterise the detector a nd the results obtained so far.\n\nhttps://indico.inp.nsk.su/event/20/cont ributions/811/ LOCATION: URL:https://indico.inp.nsk.su/event/20/contributions/811/ END:VEVENT BEGIN:VEVENT SUMMARY:ATLAS Forward Proton Time-of-Flight Detector - LHC Run2 performanc e and experiences DTSTART;VALUE=DATE-TIME:20200226T033000Z DTEND;VALUE=DATE-TIME:20200226T035000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-812@indico.inp.nsk.su DESCRIPTION:Speakers: Tomáš SÝKORA (Institute of Particle and Nuclear P hysics\, Faculty of Mathematics &\; Physics\, Charles University)\nThe performance of the ATLAS Forward Proton Time-of-Flight (ToF)\nCherenkov de tector is shown using the ATLAS collaboration data collected\nin the 2017 running period of the LHC Run2.

It is built from individual modules (0.5 m × 4.8 m) comprised of 8 scintillating fibre mats with a length of 2.4 m as the active detector material. The 13 cm wide fibre mats consist o f 6 layers of densely packed blue emitting scintillating fibres. The scint illation light is detected with arrays of multi-channel silicon photomulti pliers (SiPMs) cooled to -40C to minimize the expected high dark noise fro m neutron radiation. The readout of 524k channels occurs through custom-d esigned front-end electronics.\n\nSince it is the first time that this tec hnology is been used as a large tracker and with a small granularity many challenges has to be overcome.

A general trend is to use for detectors the elements pr oduced from the selected top-quality grade scintillation materials instead of expensive novel chemically not stable halides. Another trend\, which came in the last few years\, is to apply new achievements from the theory of scintillation materials to engineer the properties of the materials for a particular application [2]. From that point of view\, the complex oxide s with garnet structure is a family of materials\, for which properties ca n be tuned for the best price/performance ratio for a particular applicati on. \n\nThe combination of the scintillation properties\, particularly the high light yield and high time resolution of garnet crystals with modern SiPM photosensors\, with outstanding radiation hardness and chemical and m echanical stability make the complex garnet oxides the candidates of choic e for a range of various applications in HEP experiments. Doped with Ce\, the yttrium Y or Gd-based garnets could be produced by the well-establish ed Czochralski crystal growth technique and can be produced at a quantity to equip detectors consisting of thousands and thousands of heterogeneous cells. Garnet crystals with a large quantity of Gd could be utilized for neutron detection in a large energy range. Due to its cubic crystalline s tructure\, the garnet may be obtained as a polycrystalline ceramic using v arious techniques\, including 3D-printing [3]\; this further widens the ra nge of the possible applications.\n\nHere we report on the series of devel opments\, in lines with the Grant No. 14.W03.31.0004 of Russian Federation Government and Crystal Clear Collaboration at CERN\, on multicationic gar net structure scintillation materials. Their prospects for an application in “shaslyk”\, “spaghetti”\, neutron and “mip” detectors at fu ture HEP experiments are discussed.\n\n1.

In 2019\, the existing system of scintillation detector st ations was extended with 3 stations of the new type Taiga-Muon counters. E ach station contains 16 counters\, with 8 surface and 8 underground counte rs. The counter and station positioning has been studied using specially d eveloped Monte Carlo simulation program based on of CORSIKA and GEANT4 sof tware packages. \nThis simulation study is concentrated on the ultrahigh e nergy extensive air showers (EAS) induced by gamma-quanta or proton in the range from 1 PeV to 10 PeV and zenith angle ranging 00 - 450. The simulat ion results are analyzed with the help of neural network. For this work\, a set of air showers was created by CORSIKA. The list of useful secondary particles at the ground level is produced using the COAST library package. The interaction of secondary particles with the soil and detectors was si mulated with GEANT4 package.\nIt is known\, that the lateral distributions of particle density in gamma-quanta and proton EAS are different at the g round level. Also the density of muons is different. To use both these cha racteristics for separation of gamma-quanta from proton we suggest using a neural network. The method called binary cross entropy was studied. Ampli tudes in surface and underground counters of each station were given as in put data. The air shower having energy ranging 2.25 - 3.5 PeV shows more t han 90% of identification efficiency for proton by keeping identification efficiency of gamma around 50%.\n\nhttps://indico.inp.nsk.su/event/20/cont ributions/862/ LOCATION: URL:https://indico.inp.nsk.su/event/20/contributions/862/ END:VEVENT BEGIN:VEVENT SUMMARY:GlueX DIRC at JLab DTSTART;VALUE=DATE-TIME:20200227T093000Z DTEND;VALUE=DATE-TIME:20200227T095000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-863@indico.inp.nsk.su DESCRIPTION:Speakers: Jochen Schwiening (GSI)\, Wenliang Li (College of Wi lliam and Mary)\nThe GlueX experiment at Jefferson Laboratory aims to perf orm quantitative tests of non-perturbative QCD through hadronic spectrosco py (mainly using light-quark mesons and baryons).

The most sensitive experimental probe in this respect is the search for neutrinoless double beta decay ($\\beta\\beta 0\\nu$)\, which c an only occur if the neutrino is its own antiparticle. A positive detectio n will provide a first demonstration of lepton number violation\, as well as support for theories beyond the Standard Model explaining the origin an d smallness of the neutrino mass\, and the generation of matter-antimatter asymmetry in the Universe via leptogenesis. The importance of $\\beta\\be ta 0\\nu$ detection on the one hand\, and the availability of promising ex perimental schemes with already proven results on the other\, motivate an international\, well-funded\, multi-isotope approach. \nA number of exper iments have already constrained the $\\beta\\beta 0\\nu$ half-life to $10^ {25}-10^{26}$ years\, employing masses of $\\beta\\beta 0\\nu$ isotopes of tens to hundreds of kg. If one assumes that the underlying mechanism for $\\beta\\beta 0\\nu$ is the exchange of light Majorana neutrinos\, this co rresponds to excluding effective Majorana neutrino masses slightly above t he inverted mass-ordering band in the neutrino mass parameter space. The n ext generation of experiments aims to fully explore the inverted mass orde ring region\, which requires sensitivities to half-lives of the order of $ 10^{27}-10^{28}$ years. This\, in turn\, necessitates tonne-scale masses o f the $\\beta\\beta 0\\nu$ isotopes and an order-of-magnitude improvement in background rejection. This talk will review the different technologies employed by the main $\\beta\\beta 0\\nu$ experiments\, their present stat us and plans for tonne-scale searches\, discussing\, in particular\, their key merits and respective challenges.\n\nhttps://indico.inp.nsk.su/event/ 20/contributions/865/ LOCATION: URL:https://indico.inp.nsk.su/event/20/contributions/865/ END:VEVENT BEGIN:VEVENT SUMMARY:The Experimental Program at IHEP CAS DTSTART;VALUE=DATE-TIME:20200224T030000Z DTEND;VALUE=DATE-TIME:20200224T033000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-866@indico.inp.nsk.su DESCRIPTION:Speakers: Jianchun Wang (Institute of High Energy Physics\, Ch inese Academy of Sciences)\nThe Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS) is a comprehensive research center for the study of particle physics in China.

The upgrade of the collider to the “High-Luminosity LHC” that wi ll deliver a luminosity of $5-7 \\cdot 10^{34} cm^{-2}s^{-1}$\, correspond ing to 140--200 pile-up events\, also necessitates a substantial upgrade o f the trigger system to make optimal use of the data. An important differe nce from the present system will be that after the upgrade\, information f rom the silicon strip tracker will be available already for the Level-1 Tr igger. This will allow CMS to use so-called “particle flow” objects\, i.e. signals seen not only in one subdetector but put together from all av ailable subdetectors\, resulting in much sharper cuts on trigger objects. Also\, trigger rates will rise both at Level-1 (from 100 kHz to 750 kHz) a nd at the High-Level Trigger. At the same time\, more sophisticated algori thms will be available at Level-1. To make this possible\, the latency - t he processing time available for arriving at the Level-1 trigger decision - will increase significantly. Machine-learning techniques such as Boosted Decision Trees have already started to be implemented in the trigger elec tronics and will occupy a more important place in the future. The use of H igh-Level Synthesis (HLS) tools will allow physicists to formulate trigger requirements in a language closer to that of data analysis. To avoid miss ing unexpected signatures from New Physics\, studies are underway to emplo y anomaly detection using autoencoders.\n\nhttps://indico.inp.nsk.su/event /20/contributions/885/ LOCATION: URL:https://indico.inp.nsk.su/event/20/contributions/885/ END:VEVENT BEGIN:VEVENT SUMMARY:The Drift Chamber of the MEGII experiment DTSTART;VALUE=DATE-TIME:20200225T050000Z DTEND;VALUE=DATE-TIME:20200225T052000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-890@indico.inp.nsk.su DESCRIPTION:Speakers: Gianluigi Chiarello (INFN Roma1)\, Giovanni Francesc o Tassielli (INFN Lecce &\; University of Salento)\nThe MEG experiment at the Paul Scherrer Institut searches for the charged Lepton Flavor Viola ting $\\mu^{+}\\rightarrow e^{+}\\gamma$ decay.

P recise hit-time tagging with ~5 ns resolution is required for the vertex a nd tracking detectors\, to mitigate the impact of beam-induced background on the measurement accuracy. Moreover\, a low mass of ~0.2% X0 per layer f or the vertex and ~1% X0 per layer for the tracker is needed\, combined wi th a single-plane spatial resolution of a few micrometers. To address thes e requirements\, an all-silicon vertex and tracking system is foreseen at CLIC. To this end\, a broad R&D program on new silicon detector technologi es is being pursued. For the ultra-light vertex detector\, different small pitch (25 um) hybrid technologies with innovative sensor concepts are exp lored. A dedicated 65 nm readout chip (CLICpix2) has been developed and in terconnected via fine pitch bump-bonding to thin planar sensors. Furthermo re\, alternative interconnects such as bonding using anisotropic conductiv e films (ACF) are explored. Various Silicon On Insulator (SOI) test chips are also under study. For the large-scale silicon tracker\, fully monolith ic CMOS technologies are considered. CMOS sensors with a large collection electrode have been extensively studied in various test-beam campaigns. Ba sed on 3D TCAD simulations and previous test results\, innovative concepts for CMOS sensors with a small collection electrode have been developed an d implemented in various prototype chips targeting CLIC and other future p rojects.

Main triggers used during Run 2 (2015-2018) for those physics studies were a single-electron trigger with ET threshold around 25 GeV and a diphoton trigger with thresholds at 25 an d 35 GeV.

To cope with ever-increasing luminosity and more challenging pile-up conditions a t the LHC\, the trigger selections needed to be optimized to control the r ates and keep efficiencies high.

The scintillators are read out by wavele ngth shifting fibres to photomultiplier tubes (PMTs) at the back of each w edge-shaped calorimeter module. The analogue signals from the PMTs are amp lified\, shaped\, and digitised on the detector every 25 ns\, and stored o n detector in digital pipeline buffers until a trigger decision is receive d. The data are then read out to the off-detector systems for further proc essing.\n\nTileCal employs several calibration systems that\, together wit h the collected collision data\, provide the basis for response equalisati on and monitoring at each stage of the readout path\; from scintillation l ight production to energy and time reconstruction. Furthermore\, the calor imeter performance has been established with large samples of proton-proto n collision data during LHC Run 1 and Run 2. The high-momentum isolated mu ons have been used to study and validate the electromagnetic scale\, while hadronic response has been probed with isolated hadrons. The calorimeter time resolution has been studied with multi-jet events.\n\nWe present and summarise results of the calorimeter calibration and performance.\n\nhttps ://indico.inp.nsk.su/event/20/contributions/922/ LOCATION: URL:https://indico.inp.nsk.su/event/20/contributions/922/ END:VEVENT BEGIN:VEVENT SUMMARY:Novel focal plane detector concepts for the NSCL/FRIB S800 spectro meter DTSTART;VALUE=DATE-TIME:20200225T060000Z DTEND;VALUE=DATE-TIME:20200225T062000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-923@indico.inp.nsk.su DESCRIPTION:Speakers: Marco Cortesi (NSCL)\nThe NSCL/FRIB S800 superconduc ting spectrograph is used for studying nuclear reaction induced by high-en ergy radioactive beams. The spectrometer was designed for high-precision m easurements of small scattering angles (within ±2 msr)\, combined to larg e acceptance of the solid angle (20 msr) and momentum (6%). The high-resol ution (1/10\,000) is optimized for energies up to 200 MeV/u. The S800 has been an indispensable apparatus for the wide physics program of the NSCL w ith fast rare isotope beams\, being the most heavily-used experimental dev ice at NSCL. The S800 spectrograph will continuous to serve the nuclear ph ysics/astrophysics community for experiments with rare isotope beams also during FRIB operation. \nA crucial component for the performance of the S8 00 spectrometer is the focal plane detector system\, which consists of an array of various detector technologies for trajectory reconstruction as we ll as particle identification (PID). This includes two x/y drift chambers for tracking\, an ionization chamber for atomic number identification by e nergy loss measurement\, and a plastic scintillator for timing (as well as energy loss). Downstream the plastic scintillator\, a CsI(Na) hodoscope i s deployed to identify atomic charge states of the implanted nuclei via to tal kinetic energy (TKE) measurement. \nIn this work\, the operational mec hanism and performance of a novel detector concepts planned for the upgrad e of the S800 focal plane are described for the first time. In particularl y\, we will present the design of the new drift chamber (DC) readout based on a hybrid Micro-Pattern Gaseous Detector structure. Performance evaluat ions under irradiation with small lab source (5.6 MeV alpha–particle emi tted by an Am-241 source) as well as with test heavy-ion beams will be pre sented and discussed in detail. In the latter case we the detector was irr adiated by a 78Kr36+ beam at around 150 MeV/u\, as well as by a heavy ion fragmentation cocktail produced by the 78Kr beam impinging on a Be target. \nIn addition\, we will present the development of a heavy-ion particle id entification (PID) device based on an energy-loss measurement (ΔE) within a novel optical scintillation scheme. The new instrument consists of a mu lti-segmented optical detector (OD) filled with high-luminescence yield ga s (e.g. pure Xenon). Its operational principle is based on recording the f ast scintillation light emitted along an ion’s track. This developing te chnology allows for high-resolution ΔE measurements at high counting rate \, unlike traditional ionization chambers. Both high energy resolution and high counting rate capabilities are needed to take full advantage of the future FRIB’s rare-isotope beam portfolio and anticipated high intensity . The proposed detector presents a significant advance in both instrumenta tion and capabilities in the field of experimental nuclear physics\, provi ding new opportunities for experiments with rare isotope beams.\n\nhttps:/ /indico.inp.nsk.su/event/20/contributions/923/ LOCATION: URL:https://indico.inp.nsk.su/event/20/contributions/923/ END:VEVENT BEGIN:VEVENT SUMMARY:The MIP Timing Detector for the CMS Phase II Upgrade DTSTART;VALUE=DATE-TIME:20200226T031000Z DTEND;VALUE=DATE-TIME:20200226T033000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-924@indico.inp.nsk.su DESCRIPTION:Speakers: Mehmet Ozgur Sahin (CEA Saclay Irfu)\nThe Compact Mu on Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is unde rgoing an extensive Phase-II upgrade program to cope with the challenging conditions of the future High-Luminosity LHC (HL-LHC).

Particle identification (PID) of the final state hadrons is a key req uirement for EIC.

Th e sensitive detector of the CEPC DHCAL is required to be compact and highl y efficient for MIPs with low number of hits per MIP track (hit multiplici ty). GEM and WELL-THGEM detectors have been investigated as options for th e DHCAL sensitive detector. A GEM detector with only two GEM layers (doubl e-GEM) was proposed to make the detector more compact than the usual tripl e-GEM detector. A 30 cm× 30 cm double- GEM prototype was built with the s elf-stretching technique to study the performance of the double-GEM detect or for application to the CEPC DHCAL. The double-GEM prototype was read ou t with the Microroc chip that has been developed specifically for the appl ication of MPGDs to DHCALs\, and was tested with cosmic-rays. The results of the test show a detection efficiency higher than 95% for MIPs was obtai ned\, and hit multiplicity was about 1.2. However\, the double-GEM detecto r made by the self-stretching technique has a dead area of about 10% at th e four edges of the detector\, which turned out to be hardly reduced. The WELL-THGEM detector is advantageous to the GEM detector in minimizing the dead area due to its simple assembly without stretching. In addition\, it has a more compact structure than the double-GEM detector thanks to use of single-stage gas amplification and no induction gap. A 25 cm× 25 cm resi stive WELL-THGEM prototype was developed with the DLC coating and thermal bonding techniques\, where the former technique was used to make resistive layers for the prototype and the latter was used to bond the THGEM layer and the anode PCB together. Besides\, a fast grounding circuit was designe d on the anode to enhance the rate capability of the detector. Preliminary results from tests of the WELL-THGEM with X-rays show the gain of the det ector could reach 8000 with a 20% uniformity\, and the detector could main tain such a gain when irradiated with 8 keV X-ray at a rate of 300 kHz/cm2 . Based on these results\, the WELL-THGEM detector looks a promising MPGD as the sensitive detector of the CEPC DHCAL\, which merits further studies .\n\nhttps://indico.inp.nsk.su/event/20/contributions/937/ LOCATION:zoom remote URL:https://indico.inp.nsk.su/event/20/contributions/937/ END:VEVENT BEGIN:VEVENT SUMMARY:Current and Future FPGA-TDC Developments at GSI DTSTART;VALUE=DATE-TIME:20200225T090000Z DTEND;VALUE=DATE-TIME:20200225T092000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-941@indico.inp.nsk.su DESCRIPTION:Speakers: Michael Traxler (GSI Helmholtzzentrum für Schwerion enforschung GmbH)\nHigh precision time measurements as well as pulse width encoded charge measurements are a crucial element in particle identificat ion detectors.\nFPGA based time-to-digital converters have been proven to be very useful devices for this task.\n\nThe design efforts at GSI lay spe cial emphasis on providing low and lowest cost platforms for TDCs.

It exploits\nthe 550 Me V positron beam provided by the DAΦNE LINAC impinging on a\nthin target.\ nThe primary beam crosses a diamond target and if it does not interact it\ nis bent by a magnet in between the end of the spectrometer and the calori me-\nter\, thus leaving the experiment undetected. If any kind of interact ion causes\nthe positron to lose more than 50 MeV of energy\, the magnet b ends it into the\nspectrometer acceptance\, providing a veto signals again st bremsstrahlung back-\nground. In case of annihilation\, the accompanyin g ordinary photon is detected\nby the electromagnetic calorimeter regardle ss of the A 0 decay products. A single\nkinematic variable characterizing the process\, the missing mass\, is computed\nusing the formula: M2 miss = (P beam + P e − − P γ ) 2\n\nIts distribution should peak at M A 2 0 for A 0 decays\, at zero for the concurrent\ne + e → γγ process\, and should be smooth for the remaining background.\nTo measure such a reactio n\, the PADME apparatus has been built at the Frascati\nNational Laborator y of INFN. It consists of a small scale detector composed of\nthe followin g parts:\n\n• a diamond active target\, to measure the position and the intensity of the\nbeam in each single bunch\;\n\n• a beam monitor system consisting of two different silicon-pixel detectors.\nThe first one\, loc ated at the beam entrance\, can be inserted in place of\nthe target to tun e beam parameters\; the second\, located on the beam exit\ntrajectory\, mo nitors the beam spot during the data taking\;\n\n• a spectrometer\, to m easure the charged particles momenta in the range\n50-400 MeV\;\n\n• a d ipole magnet\, to deflect the primary positron beam out of the spec-\ntrom eter and the calorimeter and to allow momentum analysis\;\n\n• a vacuum chamber\, to minimize the unwanted interactions of primary and\nsecondary particles\;\n\n• a finely segmented\, high resolution electromagnetic ca lorimeter\, to measure\n4-momenta and veto final state photons.\n\nEach el ement has specific requirements that are stringent and sometimes at the\nl imit of present technology.\nA commissioning run has been performed betwee n 2008 and 2019\, and in Febru-\nary 2020 the experiment is expected to ta ke data for two months.\nThe talk will give an overview of each detector c omponent and a description\nof the chosen technical solutions implemented to accomplish the experiment\nneeds.

The physics target of the e xperiment is to improve measurement of rare B meson decays with better and higher luminosity. An aerogel-based proximity focusing ring-imaging Chere nkov (ARICH) counter is utilized for charged particle identification (PID) in the forward end-cap region. For the study of CP violation involved in B decays\, the goal is to separate kaons from pions up to and above 4σ fo r momenta up to 4 GeV/c. The counter is made of aerogel tiles to generate Cherenkov photons\, and a 144-channel Hybrid Avalanche Photo Detector (HAP D) is adopted as a photo-detector. The HAPD signal is digitized by using t he Application Specific Integrated Circuit (ASICs). Two different types of Field Programmable Gate Array (FPGA) boards are responsible for data proc essing and acquisition. In the Phase 3 (SuperKEKB beam collision from Apr. to Dec. 2019)\, the ARICH system have been operating smoothly\, and softw are algorithm has been validated with the data as well. We will present th e status of the entire hardware system during Phase 3 operation and the pr eliminary result of PID performance.\n\nhttps://indico.inp.nsk.su/event/20 /contributions/958/ LOCATION: URL:https://indico.inp.nsk.su/event/20/contributions/958/ END:VEVENT BEGIN:VEVENT SUMMARY:Collider experiments at BINP DTSTART;VALUE=DATE-TIME:20200224T020000Z DTEND;VALUE=DATE-TIME:20200224T023000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-962@indico.inp.nsk.su DESCRIPTION:Speakers: Pavel Logachev (BINP)\nhttps://indico.inp.nsk.su/eve nt/20/contributions/962/ LOCATION: URL:https://indico.inp.nsk.su/event/20/contributions/962/ END:VEVENT BEGIN:VEVENT SUMMARY:CERN activities and plans in HEP DTSTART;VALUE=DATE-TIME:20200224T043000Z DTEND;VALUE=DATE-TIME:20200224T050000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-963@indico.inp.nsk.su DESCRIPTION:Speakers: Eckhard Elsen (CERN)\nhttps://indico.inp.nsk.su/even t/20/contributions/963/ LOCATION: URL:https://indico.inp.nsk.su/event/20/contributions/963/ END:VEVENT BEGIN:VEVENT SUMMARY:Timing characterization of 3D-trench silicon sensors DTSTART;VALUE=DATE-TIME:20200226T051000Z DTEND;VALUE=DATE-TIME:20200226T053000Z DTSTAMP;VALUE=DATE-TIME:20261014T221704Z UID:indico-contribution-20-965@indico.inp.nsk.su DESCRIPTION:Speakers: Adriano Lai (Istituto Nazione Fisica Nucleare (INFN) – Italy)\, Alessandro CARDINI (INFN Sezione di Cagliari)\nFuture tracki ng detectors have to be both space and time measuring devices at the singl e pixel level. This is strongly motivated by the extremely high interactio n intensities foreseen in the collider experiments of the next couple of d ecades and possibly beyond. Presently\, no satisfactory technical solution s are available and important development programs have started in this di rection. Minimal requirements are: the capability to sustain fluences grea ter than some 1016 1 MeV neq cm-2 and radiation doses of some Grad\, space resolutions around 10 µm and time resolutions below 50 ps.\n\n3D silicon sensors are well known [1] for their very high radiation hardness (some 1 016 n/cm2 [2]) and have intrinsic characteristics which can be exploited f or fast response. During last year\, tests have been made by the TIMESPOT collaboration on developed 55-µm-pitch 3D-trench sensor prototypes\, givi ng extraordinarily good results in terms of timing. The tests have been pe rformed both in the laboratory under a 1030 nm pulsed laser beam and under minimum ionizing particle beam at the PSI laboratories (Paul Scherrer Ins titute\, Villigen\, Switzerland). The tests yield values of time resolutio n of the order and below 30 ps rms. Such results indicate that\, as of tod ay\, these devices are possibly the only ones capable to satisfy the compl ete set of system requirements for a future vertex detector and can be con sidered a very interesting solution to be further developed and finalized. An optimized new batch of sensors is under development and will be submit ted early 2020.\n\nThis paper will describe the characteristics of the dev eloped sensors\, the kind of measurements performed and will discuss the r esults obtained. The ongoing activity about further 3D sensor and fast fro nt-end electronics developments will be also briefly illustrated.\n\n[1] C .
