The system effectively uses available heterogeneous resou rces for data storing and processing. Two type of the resources are used: local computing cluster\, dedicated to CMD-3 data storage and processing\, and dynamically allocated resources of supercomputers at BINP\, SSCC and NUSC. A uniform data processing cloud\, a CMD-3 Cloud\, with transparent u ser access and HTCondor as the batch system is organized over available se t of different resources. Dedicated level of software\, Large File Catalog (LFC)\, is used for data storage and access. The local cluster nodes are used as the main repository for detector data. Additional storage at BINP supercomputer is used for data caching and as temporal working space. LFC provides universal interface for data access\, using XROOTD or SSH as tran sport protocol. If neccessary\, the management level of the CMD-3 Cloud sy stem dynamically allocates resources at supercomputers with the help of vi rtualization technology.

LHCb is a single-arm spectrometer with a forward angular co verage from approximately 10 mrad to 300 mrad. It comprises a calorimeter system composed of four subdetectors [3]\, selecting transverse energy had ron\, electron and photon candidates for the first trigger level (L0)\, wh ich makes a decision 4 μs after the interaction. It provides the identifi cation of electrons\, photons and hadrons as well as the measurement of th eir energies and positions. The set of constraints resulting from these fu nctionalities defines the general structure and the main characteristics o f the calorimeter system and its associated electronics. A classical struc ture of an electromagnetic calorimeter (ECAL) followed by a hadron calorim eter (HCAL) has been adopted. In addition the system includes in front of them the Scintillating Pad Detector (SPD) and Pre-Shower (PS)\, which are two planes of scintillating pads separated by a 2.5 radiation length lead sheet\, aimed at tagging the electric charge and the electromagnetic natur e of the calorimeter clusters for the first level of trigger. ECAL\, PS an d SPD account for about 6000 channels each with three degrees of granulari ty\, concentric around the beam pipe\, namely\, the inner\, the middle and the outer parts. HCAL is made of about 1500 channels and is divided into two parts only. All four detectors are arranged in pseudo-projective geome try and follow the general principle of reading the light from scintillato r tiles with wave-length shifting fibers\, and transporting the light towa rds photomultipliers\, all following the 25 ns readout.\nThe calorimeter h as been pre-calibrated before its installation in the pit\, and the calibr ation techniques have been tested with the data taken in 2010. During oper ation\, hadronic\, leptonic and photon triggers of particular interest for hadronic B decays and radiative decays were provided by the calorimeter s ystem.\nThe design and construction characteristics of the LHCb calorimete r will be recalled. Strategies for monitoring and calibration during data taking will be detailed in all aspects. Scintillating fibres\, plastics an d photomultipliers suffer from ageing due to radiation damage or high curr ents. Different methods which are used to calibrate the detectors and to r ecover the initial performances will be presented. The performances achiev ed will be illustrated in selected channels of interest for B physics.\nRe ferences: \n[1] LHCb Collaboration\, The LHCb Detector at the LHC\, JINST 3 S08005 (2008)\, and references therein.\n[2] LHCb collaboration\, A larg e Hadron Collider Beauty experiment\, Technical Proposal\, CERN/LHCC 1998- 004.\n[3] LHCb Collaboration\, LHCb calorimeters Technical Design Report\, Technical Design Report\, CERN/LHCC 2000-036.\n\nhttps://indico.inp.nsk.s u/event/0/contributions/3/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/3/ END:VEVENT BEGIN:VEVENT SUMMARY:A Time Projection Chamber for the International Linear Collider DTSTART;VALUE=DATE-TIME:20140226T022500Z DTEND;VALUE=DATE-TIME:20140226T025000Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-4@indico.inp.nsk.su DESCRIPTION:Speakers: Paul Colas (CEA/Irfu Saclay)\nThe International Larg e Detector (ILD) is one detector concept at the ILC where calorimetry and tracking systems are combined.

The neutron-antin eutron pair production events can be detected only by the calorimeters. In the barrel calorimeter the antineutron annihilation typically occurs by 5 ns or later after beams crossing. For identification of such events it is necessary to measure the time of flight of particles to the LXe-calorimet er with accuracy of about 3 ns. The LXe-calorimeter consists of 14 layers of ionization chambers with anode and cathode readout.\nThe duration of ch arge collection to the anodes is about 4.5 mks\, while the required accura cy of measuring of the signal arrival time is less than 1/1000 of that. Be sides\, the signal shapes differ substantially from event to event\, so th e signal arrival time is measured in two stages. At the first stage\, the signal arrival time is determined with an accuracy of 1-2 discretization p eriods\, and initial values of parameters for subsequent fitting procedure are calculated. At the second stage\, the signal arrival time is determin ed with the required accuracy by means of fitting of the signal waveform w ith a template waveform. To implement that\, a special electronics has bee n developed which performs waveform digitization and On - Line measurement of signals' arrival times and amplitudes.\n\nhttps://indico.inp.nsk.su/ev ent/0/contributions/19/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/19/ END:VEVENT BEGIN:VEVENT SUMMARY:Study of focusing aerogels with electron beam DTSTART;VALUE=DATE-TIME:20140227T023000Z DTEND;VALUE=DATE-TIME:20140227T025500Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-21@indico.inp.nsk.su DESCRIPTION:Speakers: Sergey Kononov (Budker Institute of Nuclear Physics SB RAS)\nRecent results from the beam test of the FARICH detector prototyp es at the BINP electron beam line are reported.

This technology combines si gnal detection and amplification in a single silicon pixel structure\, so that the position measurement of traversing particles can be achieved with an overall material budget of 0.075% radiation length\, corresponding to 75 μm² in order to minimize the impact of multiple scattering for low tr ansverse momentum tracking. Moreover\, the DEPEFT detector has an excellen t signal-to-noise ratio\, low power consumption and offers a non-destructi ve readout.\nThe instantaneous luminosity of 8x10³⁵ cm⁻²s⁻¹ expec ted at SuperKEKB increases the event rate and causes a large background. T he close proximity of the pixel detector to the beampipe (only 1.4 cm from the interaction point) poses many challenges to the detector technology\, in particular to radiation hardness and electronics. The vertex pixel det ector consists of two DEPFET layers (radii at 14 mm and 22 mm).\nThese are 20 ladders in total corresponding to 8 Mega Pixels (pixel sizes: 50x55 μ m² and 50x75 μm²). The four-fold readout in rolling shutter mode result s in a total readout time of about 20 μs for an entire frame.

It must be capable of fast patter n recognition and track reconstruction and will be required to drive data to the outside world at speeds of up to 3 Tbit/s. This challenge is being met with a new VELO design based on hybrid pixel detectors positioned to w ithin 5 mm of the LHC colliding beams. The sensors have 55 x 55 μm square pixels and the VELOPix ASIC which is being developed for the readout is b ased on the Timepix/Medipix family of chips.\nThe hottest ASIC will have t o cope with pixel hit rates of up to 900 MHz.\nThe material budget will be optimised with the use of evaporative CO₂ coolant circulating in microc hannels within a thin silicon substrate.\nMicrochannel cooling brings many advantages: very efficient heat transfer with almost no temperature gradi ents across the module\, no CTE mismatch with silicon components\, and low material contribution. This is a breakthrough technology being developed for LHCb.\nLHCb is also focussing effort on the construction of a lightwei ght foil to separate the primary and secondary LHC vacua\, the development of high speed cables\, and the metallisation and radiation qualification of the module.\nThe 40 MHz readout will also bring significant conceptual changes to the way in which the upgrade trigger is operated.

Scint illation light produced in the tiles is transmitted by wavelength shifting fibers to photomultiplier tubes (PMTs).\nThe resulting electronic signals from approximately 10000 PMTs are measured and digitized before being tra nsferred to off-detector data-acquisition systems.\nAfter an initial setti ng of the absolute energy scale in test beams with particles of well-defin ed momentum\, the calibrated scale was transferred to the rest of the dete ctor via the response to radioactive sources. The calibrated scale was val idated in situ with muons and single hadrons and the timing performance wi th muons and jets as detailed in this contribution.\nThe data quality proc edures used during the LHC data-taking and the evolution of the detector s tatus are exposed. The energy and the time reconstruction performance of t he digitized signals is presented and the noise behavior and its improveme nt with the detector consolidation in maintenance periods are shown.\nA se t of calibration systems allow the monitoring and the equalization of the calorimeter channels response via signal sources that act at every stage o f the signal path\, from scintillation light to digitized signal.\nThese p artially overlapping systems are described in detail\, their individual pe rformance is exposed as well as comparative results on the response evolut ion of the calorimeter with time during the full LHC data-taking period. T he procedure of setting the absolute energy scale for channels/cells is de scribed and the challenge of preserving it at the % level during 3 years o f LHC collision data is described.\nIts main upgrade will occur for the Hi gh Luminosity LHC phase (phase 2) where the peak luminosity will increase 5-fold compared to the design luminosity (10³⁴ cm⁻²s⁻¹) but with maintained energy (i.e. 7+7 TeV). An additional increase of the average lu minosity with a factor of 2 can be achieved by luminosity leveling. This u pgrade will probably happen around 2022.\nThe TileCal upgrade aims at repl acing the majority of the on- and off-detector electronics so that all cal orimeter signals are directly digitized and sent to the off-detector elect ronics in the counting room. To achieve the required reliability\, redunda ncy has been introduced at different levels. Three different options are p resently being investigated for the front-end electronic upgrade. Which on e to use will be decided after extensive test beam studies. 10 Gbps optica l links are used to read out all digitized data to the counting room while 5 Gbps down-links are used for synchronization\, configuration and detect or control.

It has been developed for p article identification in the barrel region of the Belle II spectrometer\, which will probe new physics beyond the Standard Model with a luminosity of 8x10³⁵/cm²/s. The TOP detector is intended to achieve good π/K sep aration in the momentum range up to around 3 GeV/c under the high-luminosi ty environment.\nThe detector construction has been started and the remain ing development is being finalized toward the installation into the spectr ometer in early 2015.\nA single detector module mainly consists of a synth etic silica plate\, as the Cherenkov radiator\, and an array of micro-chan nel plate (MCP) photomultiplier tubes (PMTs) with readout electronics. Opt ical components for the first detector module are being delivered one afte r another. The delivered components are in process of optical inspections and assembly preparation. Mass production of the MCP-PMTs is on going smoo thly. The performance details are being inspected under the operational ma gnetic field of 1.5 T. Although the lifetime of an MCP-PMT has been an iss ue concerning the high-luminosity environment\, atomic layer deposition on MCPs has improved the lifetime significantly. Development of the readout electronics is being finalized. Their high-speed waveform sampling ASICs a nd circuit board stacks are in preproduction. Preproduction for the mechan ical structure of a detector module is about to start. It is crucial to es tablish the optical and electrical contacts between the optics\, MCP-PMTs and readout electronics.

In order to reach a sensitivity of bett er than 10⁻¹⁶\, more than 10⁹ muon decays per second have to be obs erved over a running time of one year. Precise determination of particle m omentum\, vertex position and time are necessary for background suppressio n. These requirements can be met by combining an ultra-lightweight tracker based on High-Voltage Monolithic Active Pixel Sensors (HVMAPS) with a tim ing system which consists of a scintillating fiber detector and a tile hod oscope. As the momentum of particles from muon decay is below 53 MeV/c\, t he silicon pixel tracker resolution is dominated by multiple Coulomb scatt ering. This leads to extreme requirements for the material budget of the t racking detector of below 0.1% of a radiation length per layer. Even thoug h the target power consumption of the HVMAPS detector is as low as 150 mW/ cm²\, the detector cooling must be very efficient and at the same time av oid adding material inside the active tracking volume. In this presentatio n the ultra-lightweight support structure and the gaseous helium cooling s ystem for the thin silicon pixel tracker will be discussed.\n\nhttps://ind ico.inp.nsk.su/event/0/contributions/54/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/54/ END:VEVENT BEGIN:VEVENT SUMMARY:ILC project DTSTART;VALUE=DATE-TIME:20140224T052500Z DTEND;VALUE=DATE-TIME:20140224T060000Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-55@indico.inp.nsk.su DESCRIPTION:Speakers: Hitoshi Yamamoto (Tohoku University)\nWe overview th e physics opportunities provided by the ILC project\, and briefly summariz e the current status and future prospects.\n\nhttps://indico.inp.nsk.su/ev ent/0/contributions/55/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/55/ END:VEVENT BEGIN:VEVENT SUMMARY:ATLAS Minimum Bias Trigger Scintillator upgrade for LHC RunII DTSTART;VALUE=DATE-TIME:20140228T110000Z DTEND;VALUE=DATE-TIME:20140228T112000Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-56@indico.inp.nsk.su DESCRIPTION:Speakers: Antonio Sidoti (Istituto Nazione Fisica Nucleare Sez ione Roma La Sapienza)\nThe Minimum Bias Trigger Scintillators (MBTS) deli vered the primary triggers for selecting events from real LHC collisions w ith the smallest bias for the low luminosity LHC RunI fills from 2009-2013 (proton-proton\, lead-lead and lead-proton collisions).

Heavy hadrons are identified through their flight distan ce in the Vertex Locator (VELO)\, and hence the detector is critical for b oth the trigger and offline physics analyses.\nThe VELO is the retractable silicon-strip detector surrounding the LHCb interaction point. It is loca ted only 7 mm from the LHC beam during normal LHC operation\, once moved i nto its closed position for each LHC fill when stable beams are obtained. During insertion the detector is centred around the LHC beam by the online reconstruction of the primary vertex position. Both VELO halves comprise 21 silicon micro-strip modules each. A module is made of two n+-on-n 300 m um thick half-disc sensors with R-measuring and Phi-measuring micro-strip geometry\, mounted on a carbon fibre support paddle. The minimum pitch is approximately 40 mum. The detector is also equipped with the only n-on-p s ensors operating at the LHC.\nThe detectors are operated in vacuum and a b i-phase CO2 cooling system is used. The signals read out with analogue fro nt-end chips are subsequently processed by a set of algorithms in FPGA pro cessing boards.\nThe VELO has been performing very successfully during the first run of the LHC in 2010-12.\nPossible effects of radiation damage ha ve been monitored and studied in detail throughout this period. Indeed the VELO module sensors receive a large and non-uniform radiation dose having inner and outer radii of only 7 and 42 mm\, respectively. A maximum dose of 1.2 x 1014 1 MeV neutron equivalent /cm2 was received in the innermost region of the sensors for the combined 2010-12 run I (3.4 fb-1 of delivere d data). Being operated in an extreme and highly non-uniform radiation env ironment\, type-inversion of the inner part of the n-on-n sensors has alre ady been measured.\nThe radiation damage in the detector is monitored and studied in three ways: (1) dependence of sensor currents on voltage and te mperature\; (2) measurement of the effective depletion voltage of the sens ors from the charge collection efficiency and from studying the noise vers us voltage behaviour\; and (3) cluster finding efficiency. Results will be presented in all three areas with the most recent results from the full r un I.\n\nhttps://indico.inp.nsk.su/event/0/contributions/62/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/62/ END:VEVENT BEGIN:VEVENT SUMMARY:RD51 Collaboration and MPGD Developments: Five Years Experience an d Future Plans DTSTART;VALUE=DATE-TIME:20140228T051500Z DTEND;VALUE=DATE-TIME:20140228T054500Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-64@indico.inp.nsk.su DESCRIPTION:Speakers: Eraldo Oliveri (CERN)\nDriven by the availability of modern photolithographic techniques\, the Micro Pattern Gas Detectors (MP GD) have been introduced in the last years of the 20th century by pioneer activities: Gas Electron Multipliers (GEM) and Micromegas\, later followed by thick-GEM\, resistive GEM (RETGEM) and novel micro-pattern devices.

It reduces the event rate from an inp ut of 15 MHz to around 5 kHz. To maximize efficiencies and minimize biases \, the trigger is designed around inclusive selection algorithms\, culmina ting in a novel boosted decision tree which enables the efficient selectio n of beauty hadron decays based on a robust partial reconstruction of thei r decay products. The performance of the LHCb trigger during Run 1 of the LHC is presented. In order to improve performance\, the LHCb upgrade aims to significantly increase the rate at which the detector will be read out\ , and hence shift more of the workload onto the high-level trigger. It is demonstrated that the current high-level trigger architecture will be able to meet this challenge\, and the expected efficiencies in several key cha nnels are discussed in context of the LHCb upgrade.\n\nhttps://indico.inp. nsk.su/event/0/contributions/72/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/72/ END:VEVENT BEGIN:VEVENT SUMMARY:The array for the detection of the neutron component of extensive air showers DTSTART;VALUE=DATE-TIME:20140225T101500Z DTEND;VALUE=DATE-TIME:20140225T104500Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-73@indico.inp.nsk.su DESCRIPTION:Speakers: Dmitry Gromushkin (National Research Nuclear Univers ity MEPhI)\nThe idea of the array consists in registration of delayed ther mal neutrons generated by hadronic component of extensive air showers (EAS ).

Physical Ins titute)\nAt the future Belle II experiment the inner DEPFET (DEPleted Fiel d Effect Transistor) pixel detector will consist of ~8 million channels. B ecause of its small distance to the interaction region and the high lumino sity in Belle II\, for a trigger rate of ~30 kHz with an estimated occupan cy of ~3% a data rate of ~22 GB/s is expected. Due to the high data rate a reduction factor higher than 30 is needed to achieve the specifications o f the event builder.\nThe main hardware to reduce the data rate is an ATCA based Compute Node (CN) developed in cooperation between IHEP Beijing and University Giessen.\nEach node has as main component a Xilinx Virtex-5 FX 70T and uses the xTCA standard. The CN is equipped with 2x2 GB RAM \, GBit Ethernet and 4x6.25 Gb/s optical links. An additional carrier board is ab le to hold up to four CN and supplies high bandwidth connections between t he four CNs and to the ATCA backplane.\nTo fulfill the required data reduc tion on the CNs Regions of Interest (ROI) are used. This regions are calcu lated in two independent systems by projecting tracks back to the pixel de tector. One is the High Level Trigger (HLT) which uses the data from the o uter detectors. The other is the Data Concentrator (DatCon) which calculat es based on Silicon Vertex Detector (SVD) data only to get low momentum tr acks. With this information only data inside this ROIs will be forwarded t o the event builder while data outside of this regions will be discarded.\ nThe ROI selection and the buffer managment for the data stored in RAM is implemented in VHDL\, as well as a merging system to combine the ROI data from HLT and DatCon.\nFirst results of the test beam time in january 2014 at DESY with a prototype detector and full DAQ chain will be presented.\n\ nhttps://indico.inp.nsk.su/event/0/contributions/75/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/75/ END:VEVENT BEGIN:VEVENT SUMMARY:New developments in solid state photomultipliers DTSTART;VALUE=DATE-TIME:20140227T020000Z DTEND;VALUE=DATE-TIME:20140227T023000Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-76@indico.inp.nsk.su DESCRIPTION:Speakers: Yury Musienko (Institute for Nuclear Research (RAS)) \nSolid state photon detectors have been extensively developed during rece nt years and promise to be an alternative to photomultiplier tubes.

Th e endcap calorimeter has now been upgraded to work in the CMD-3 detector a t new collider VEPP-2000. The major part of the endcap calorimeter\, the B GO crystals\, remains the same. The main upgrade is the use of silicon PIN photodiodes and new electronics. Main reason to change photosensitive dev ice is the strong non-uniform magnetic field in the endcap calorimeter vol ume and redused available space. The Hamamatsu PIN photodiode S3590-08 was chosen as the optimal solution\, as they are insensitive to magnetic fiel ds and are both compact and stable. An order of magnitude larger capacitan ce of silicon photodiodes requires design and produce new custom electroni cs. The upgrade is expected to bring an overall improvement of parameters. The endcap calorimeter has been installed in the detector and participate s in data taking which started at 2010. The preliminary energy resolution is measured in the energy range 160-1000 MeV. It is better compare to the CMD-2 detector.\n\nhttps://indico.inp.nsk.su/event/0/contributions/95/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/95/ END:VEVENT BEGIN:VEVENT SUMMARY:Micromegas detectors for the ATLAS Muon System upgrade DTSTART;VALUE=DATE-TIME:20140228T080000Z DTEND;VALUE=DATE-TIME:20140228T082500Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-96@indico.inp.nsk.su DESCRIPTION:Speakers: Andre Zibell (Julius-Maximilians-Universitaet Wuerzb urg)\nWe will present the status and the plans of the micromegas detector project for the upgrade of the ATLAS muon system in the next long LHC shut down in 2018.

MGPDs are in addition light\, well suit ed to cover large areas with\, and affordable.\nTraditionally\, gas-based detectors are simulated by integrating field gradients and transport table s. This technique is not suitable for MPGDs because the mean free path bet ween collisions\, a few μm\, is not much smaller than the smallest struct ural elements nor much smaller than the spatial resolution of the best MPG Ds.\nA more appropriate method consists in tracking electrons from molecul e to molecule and applying the various processes (elastic and inelastic co llisions\, excitation\, ionisation\, attachment).\nMagboltz contains an el aborate library of cross section terms - simulations routinely involve wel l over a hundred terms. Even if the technique is computing time intensive\ , it has eanwhile been shown to yield accurate results.\nThe method can be used to simulate space charge and charge accumulations on the surfaces of dielectrics.

Liquid argon samplin g calorimeters are used for all electromagnetic calorimetry covering the p seudorapidity region up to 3.2\, as well as for hadronic calorimetry in th e range 1.4-4.9. The electromagnetic calorimeters use lead as passive mate rial and are characterized by an accordion geometry that allows a fast and uniform azimuthal response. Copper and tungsten were chosen as passive ma terial for the hadronic calorimetry\; whereas a parallel plate geometry wa s adopted at large polar angles\, an innovative one based on cylindrical e lectrodes with thin argon gaps was designed for the coverage at low angles \, where the particles flow is higher. All detectors are housed in three c ryostats kept at 88.5 K. After installation in 2004-2006\, the calorimeter s were extensively commissioned over the three years period prior to first collisions in 2009\, using cosmic rays and single LHC beams. Since then\, around 27 fb⁻¹ of data have been collected at a unprecedented center o f mass energies between 7 TeV and 8 TeV. During all these stages\, the cal orimeter and its electronics have been operating with performances very cl ose to the specification ones.\nAfter 2019\, the instantaneous luminosity will reach 2-3×10³⁴ cm⁻²s⁻¹\, well above the luminosity for whic h the calorimeter was designed. In order to preserve its triggering capabi lities\, the detector will be upgraded with a new fully digital trigger sy stem with a refined granularity.\nIn 2023\, the instantaneous luminosity w ill ultimately reach 5-7×10³⁴ cm⁻²s⁻¹\, requiring a complete rep lacement of the readout electronics. Moreover\, with an increased particle flux\, several phenomena (liquid argon boiling\, space charge effects...) will affect the performance of the forward calorimeter (FCal). A replacem ent with a new FCal with smaller LAr gaps or a new calorimeter module are considered. The performance of these new calorimeters is being studied in highest intensity particle beams.\nThe talk will cover all aspects of the first three years of operation. The excellent performance achieved will be especially detailed in the context of the discovery of the Higgs boson an nounced in July 2012.

In most cases\, the temperature gradients nearly growth interface are in the range 40-200 K/cm. In such conditions thermoelastic stress and melt superh eating are inevitable. In some cases\, especially when it is necessary to grow large size crystals or crystals with strong anisotropy of the thermal properties and low mechanical strength\, high thermal gradients lead to t he destruction of crystals and that is a major obstacle to growth of high quality crystals. The melt superheating leads to volatility of charge comp onents\, disruption of stoichiometry and inhomogeneity functional properti es of crystal.\nIn the report the results of growth of top quality scintil lation crystals at low temperature gradient (LTG) conditions is presented. In LTG CZ technique temperature gradients are reduced by two orders of ma gnitude in comparison with the conventional crystal growth techniques.\nTh e results of growing BGO crystals large size (up to 60 kg) with high radia tion hardness are presented.\nThe advantages of use LTG CZ technique for g rowth of isotopically enriched crystals used for rare events searches are most essential. The crystal growth for these applications generally is ass ociated the use of very expensive raw materials (high radio purity\, isoto pically- enriched composition\,etc.) which is available in a very limited quantity. In addition for these projects requirements to crystal quality a re very high. Another essential requirement is a need to obtain the maximu m possible weight of a crystal from initial charge. The ossibility of the LTG technique are demonstrated on example of successful growth of isotopic ally enriched crystals 106CdWO₄ and 116CdWO₄ with duty factor about 85 % are presented.\nGrowth of large sized ZnMoO₄ crystals including develo pment of precursor's synthesis starting from Mo metal and recycling of res iduals for producing isotopically enriched Zn100MoO₄ crystals for LUMINE U project are also reported.\n\nhttps://indico.inp.nsk.su/event/0/contribu tions/112/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/112/ END:VEVENT BEGIN:VEVENT SUMMARY:Proposal for the upgrade of the tracking and trigger system of the CMD-3 detector DTSTART;VALUE=DATE-TIME:20140225T101500Z DTEND;VALUE=DATE-TIME:20140225T104500Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-113@indico.inp.nsk.su DESCRIPTION:Speakers: Lev Shekhtman (Budker Institute of Nuclear Physics)\ nLarge cylindrical triple-GEM detector (CGEM) is proposed to upgrade the C MD-3 tracker subsystem.\nCGEM is considered both for precise measurement o f z-coordinate of tracks in drift chamber (DC) and for generating signals for the first level trigger.

This tracker will improve significantly the detection efficiency for multi-hadron events\, will help to study proc esses with ISR and measure the cross section with double tagged electrons when two virtual photons radiated by initial electrons produced C-even sta tes (π⁰\, η).\n\nhttps://indico.inp.nsk.su/event/0/contributions/113/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/113/ END:VEVENT BEGIN:VEVENT SUMMARY:Development of high resolution tracking detectors with Gas Electro n Multipliers DTSTART;VALUE=DATE-TIME:20140228T090500Z DTEND;VALUE=DATE-TIME:20140228T092500Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-114@indico.inp.nsk.su DESCRIPTION:Speakers: Lev Shekhtman (Budker Institute of Nuclear Physics)\ nCascaded Gas Electron Multipliers (GEM) allow to construct detectors for charge particles tracking with high spatial resolution and rate capability .\nSuch detectors can withstand high background fluxes up to 10⁵ partic les/mm²/s and determine track coordinates with precision of 50-70 micron. These remarkable features of GEM govern the use of this technology in a n umber of experiments at the Budker Institute of Nuclear Physics.

CMD-3 is a general purpose detector designed to study e⁺e⁻ annihilation into had rons in the wide energy range\, E(c.m.s) = 0.3÷2 GeV. During 3 years of o peration detector collected integral luminosity of about 60 nb⁻¹.\nThe barrel electromagnetic calorimeter of the detector consists of two subsyst ems: closest to the beam pipe is the Liquid Xenon calorimeter (LXe) and th e outer one is based on CsI scintillation crystals (CsI). LXe calorimeter contains 400 liters of LXe\, covers a solid angle 0.8×4π and has a thick ness equals to 5.4 X₀. Finely segmented strip structure of the calorimet er electrodes provides the possibility to analyze energy deposition profil e through the shower direction\, reconstruct tracks of charged particles a nd measure total energy deposition.\nThe CsI calorimeter consists of 8 oct ants\, located around the LXe calorimeter\, and contains 1152 counters. Ea ch counter is based on CsI(Tl) or CsI(Na) crystal of 6×6×15 cm³ size th at corresponds to 8.1 X₀ in the direction transverse to the beam.\nThe t otal thickness of the barrel calorimeter is equal to 13.5 X₀.\nThe main advantage of the combined barrel calorimeter is that the LXe calorimeter a llows to measure the coordinates of gamma conversion point with spatial re solution of about 1.5 mm\, and additional 8 X₀ of crystal CsI provides t he total energy resolution of combined calorimeter of about 4.5% /1GeV.\nT he design of the calorimeter and its current performance are presented.\nT he energy calibration procedures using cosmic rays for LXe and CsI and usi ng elastic e⁺e⁻ scattering process for the LXe calorimeter are present ed in this work. The accuracy of calibration constants for LXe and CsI cal orimeters are about 2% and 3% correspondingly. Also the gamma energy recon struction is described in the work and the results of π⁰ reconstruction giving the π⁰ width of about 8% are presented.\n\nhttps://indico.inp.n sk.su/event/0/contributions/115/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/115/ END:VEVENT BEGIN:VEVENT SUMMARY:Small angle detectors for study the diffractive processes with CMS DTSTART;VALUE=DATE-TIME:20140225T094000Z DTEND;VALUE=DATE-TIME:20140225T100000Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-116@indico.inp.nsk.su DESCRIPTION:Speakers: Vladimir Samoylenko (Insitute for High Energy Physic s)\nThe aim of the Proton Precision Spectrometer (PPS) Project is to add p recision forward-proton tracking (~10 μm\, ~1 μrad) and timing (with res olution \n\nhttps://indico.inp.nsk.su/event/0/contributions/116/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/116/ END:VEVENT BEGIN:VEVENT SUMMARY:New electronics with high time and energy resolution for SND detec tor calorimeter DTSTART;VALUE=DATE-TIME:20140225T101500Z DTEND;VALUE=DATE-TIME:20140225T104500Z DTSTAMP;VALUE=DATE-TIME:20260416T210823Z UID:indico-contribution-0-117@indico.inp.nsk.su DESCRIPTION:Speakers: Ilya Surin (Budker Institute of Nuclear Physics)\nIt is planned to improve the NaI(Tl) SND electromagnetic calorimeter (EMC) w ith the new measuring channel.
