Upgrade of the front-end electronics components in the existing HE calorimeter is planned for a num ber of reasons. New charge integrator encoder (QIE11) shunt tests and DC/D C converter calibration were carried out in preparation for HE calorimeter upgrade phase 1. Analysis and measurement results for the new generation front-end electronics components are presented.\n\nhttps://indico.particle .mephi.ru/event/4/contributions/795/ LOCATION:Milan Hotel Verdi URL:https://indico.particle.mephi.ru/event/4/contributions/795/ END:VEVENT BEGIN:VEVENT SUMMARY:Geant4 simulation of optical photon transport in scintillator tile with direct readout by silicon photomultiplier DTSTART;VALUE=DATE-TIME:20161014T133000Z DTEND;VALUE=DATE-TIME:20161014T134500Z DTSTAMP;VALUE=DATE-TIME:20260814T154133Z UID:indico-contribution-96-733@cern.ch DESCRIPTION:Speakers: Sergey Korpachev (MEPhI)\nActive elements in the bas eline design of the highly granular calorimeters proposed for future colli der experiments are scintillator tiles with silicon photomultiplier readou t. The direct coupling of SiPm to scintillator is considered to be the mai n option for such detectors. In this study\, the response of scintillator- SiPm system to minimum ionizing particle was simulated using the optical p hoton transport functionality available in the Geant4 package. The model was tuned using a comparison with experimental results. The uniformity of response for flat and dimpled tile surfaces was estimated. Such simulation studies are important for optimization of detector elements not only for high-energy physics\, but also for medical applications.\n\nhttps://indico .particle.mephi.ru/event/4/contributions/733/ LOCATION:Milan Hotel Verdi URL:https://indico.particle.mephi.ru/event/4/contributions/733/ END:VEVENT BEGIN:VEVENT SUMMARY:Timing scintillation detector with SiPM incorporated throughout a scintillator’s body DTSTART;VALUE=DATE-TIME:20161014T131500Z DTEND;VALUE=DATE-TIME:20161014T133000Z DTSTAMP;VALUE=DATE-TIME:20260814T154133Z UID:indico-contribution-96-687@cern.ch DESCRIPTION:Speakers: Nikita Vozniuk (MEPhI)\nA timing scintillation detec tor based on a plastic scintillator tile sized 35x5x1 cm3 and SiPM optical readout has been developed and characterized. For the best uniformity of the detector’s response to particle hits across its area\, a set of SiPM optical sensors has been incorporated into the scintillator throughout it s volume. Time resolution better than 250 ps (sigma) has been achieved for each point of the device. Uniformity of the detector’s response is conf irmed by amplitude measurements along the tile as well as measurements of the efficiency of scintillation detection\, which\, on average\, is not wo rse than 99%.\n\nhttps://indico.particle.mephi.ru/event/4/contributions/68 7/ LOCATION:Milan Hotel Verdi URL:https://indico.particle.mephi.ru/event/4/contributions/687/ END:VEVENT BEGIN:VEVENT SUMMARY:Application of SiPM for Modern Nuclear Physics Practical Workshop DTSTART;VALUE=DATE-TIME:20161014T143000Z DTEND;VALUE=DATE-TIME:20161014T144500Z DTSTAMP;VALUE=DATE-TIME:20260814T154133Z UID:indico-contribution-96-679@cern.ch DESCRIPTION:Speakers: Olga Gavrilenko (Igorevna)\nSilicon Photo-Multiplier s (SiPM) are state of the art light detectors with very high single photon sensitivity and photon number resolving capability\, representing a break through in several fundamental and applied Science domains. So\, introduct ion of SiPM in to the education is important process increasing the number of specialists involved in the SiPM development and application. As a res ult of collaborative efforts between industry and academic institutions mo dular set of instruments based on SiPM light sensors has been developed by CAEN s.p.a. It is developed for educational purposes mainly and allows pe rforming a series of experiments including photon detection\, gamma spectr ometry\, cosmic ray observation and beta and gamma ray absorption. In addi tion\, an educational experiments based on a SiPM set-up guides students t owards a comprehensive knowledge of SiPM technology while experiencing the quantum nature of light and exploring the statistical properties of the l ight pulses emitted by a LED. The toolbox is actually an open platform in continuous evolution thanks to the contribution of the research community and cooperation with high schools.\n\nThe work was supported by a program of the ministry of education and science of The Russian Federation for hig her education establishments\, project №14.578.21.0192 (RFMEFI57816X0192 ).\n\nhttps://indico.particle.mephi.ru/event/4/contributions/679/ LOCATION:Milan Hotel Verdi URL:https://indico.particle.mephi.ru/event/4/contributions/679/ END:VEVENT BEGIN:VEVENT SUMMARY:A method for lateral localization of a compact gamma source in rad ionuclide diagnostics DTSTART;VALUE=DATE-TIME:20161014T130000Z DTEND;VALUE=DATE-TIME:20161014T131500Z DTSTAMP;VALUE=DATE-TIME:20260814T154133Z UID:indico-contribution-96-621@cern.ch DESCRIPTION:Speakers: Irina Pashkovich (MEPhI)\nTo determine the depth of the area of radiopharmaceutical accumulation a method based on simultaneou s registration of two gamma ray lines of different energies and quantitati ve comparison of the intensity of these lines on the surface of the patien t's body is developed. The most widely used medical radioisotope technetiu m-99m has two gamma-lines - 140 keV and 18 keV\, which allows one to apply the proposed method to search for the sentinel lymph nodes and non-palpab le malignant tumors in the soft tissues. The result is achieved by the qua ntitative analysis of the areas of absorption peaks of technecium-99m. A d edicated scintillation detector optimized for low energy gamma rays regist ration was designed. This miniature detector consists of a LaBr3:Ce scinti llation crystal and a silicon photomultiplier packed together is a sealed aluminum housing with a wall thickness of 0.2 mm. The proposed detector wa s used in a set of experimental studies which showed that the lateral coor dinate of the Tc-99m source can be determined with an accuracy of ± 4 mm at the depth up to 30 mm a tissue-equivalent phantom.\n\nhttps://indico.pa rticle.mephi.ru/event/4/contributions/621/ LOCATION:Milan Hotel Verdi URL:https://indico.particle.mephi.ru/event/4/contributions/621/ END:VEVENT BEGIN:VEVENT SUMMARY:The silicon photomultipliers in the detector subsystems of the Glu eX experiment DTSTART;VALUE=DATE-TIME:20161014T141500Z DTEND;VALUE=DATE-TIME:20161014T143000Z DTSTAMP;VALUE=DATE-TIME:20260814T154133Z UID:indico-contribution-96-553@cern.ch DESCRIPTION:Speakers: Vladimir Berdnikov (NRNU MEPhI)\nThe subsystem detec tors of the GlueX experiment uses the silicon photomultiplier (SiPM) photo detectors. The detectors operate in condition of 2MHz load level and up to 104 pixels «fired» with ~0.3ns time resolution.

The forward calorimeter PSD@CBM is equipped with\n SiPM . The fluence up to 10e13 n/cm2 during first months\n of the CBM experime nt at position of SiPM is expected.\n Therefore we have investigated SiPM based 10-channel prototype of\n scintillation detector module produced a t JINR by irradiating it with\n quasi-monoenergetic neutrons of peak ener gy 32 MeV and fluence ~3*10e8\n n/cm2. Secondary neutron beam was produ ced in the 7Li(p\,n)7Be neutron\n generator at the NPI cyclotron (Rez\, C zech Republic).\n\n It is shown that the module electronics remains opera tional\, but the\n noise of SiPM increased. We applied new method to moni tor changes in the\n breakdown voltage without measurement of SiPMs I-V c haracteristics. The\n method is based on measurement of the dependence of Vpp and Vrms voltage\n on the bias voltage. The proposed method can be a pplied for monitoring of\n changes in the breakdown voltage during the de tector operation and does\n not require the usage of the additional equi pment.\n\nhttps://indico.particle.mephi.ru/event/4/contributions/549/ LOCATION:Milan Hotel Verdi URL:https://indico.particle.mephi.ru/event/4/contributions/549/ END:VEVENT BEGIN:VEVENT SUMMARY:Advanced Processing of SiPM Timing Resolution DTSTART;VALUE=DATE-TIME:20161014T124500Z DTEND;VALUE=DATE-TIME:20161014T130000Z DTSTAMP;VALUE=DATE-TIME:20260814T154133Z UID:indico-contribution-96-530@cern.ch DESCRIPTION:Speakers: Dmitry Philippov (NRNU MEPHI)\nStandards analog tech nique in experimental physics doesn't allow to achieve very high timing re solutions of the detectors based on SiPMs and fast scintillators.
