General information

Name of the project: Research in high energy physics and nuclear medicine using silicon photomultipliers

Strategy for Scientific and Technological Development Priority Level: а, б, в

Goals and objectives

Project objective:

  • Developing the experimental basis and research in high energy physics using detectors based on silicon photomultipliers (SiPM) – innovative photodetectors invented in Russia
  • Developing detectors based on SiPM for medical applications
  • Creating technologies for producing SiPM providing enhanced qualities and replicability of parameters of Russian SiPM

The practical value of the study

  • We have developed silicon photomultipliers with record high efficiency of registering light.
  • The Laboratory has developed prototypes of SiPM based on the CMOS technology.
  • We have produced scintillation cells of hadron calorimeter for the detector of the future linear collider.
  • The Laboratory has developed the space veto system for the СОМЕТ experiment (J-PARC, Japan) aimed at studying muon-electron conversion. The system is based on planes made of scintillator band with light detection by SiPM.
  • We have found a new exotic charmonium-like state that we called X*(3860), decaying into a pair of D and andt-D mesons on exotic quark-like states Zb(10610) and Zb(10650). For the first time we have demonstrated that Zb(10610) and Zb(10650) are virtual states.

Education and career development:

  • We have organized 5 internships abroad for undergraduates and postgraduates.
  • 9 researchers have completed professional training and career enhancement in «Silicon photomultiplier».
  • 2 doctoral dissertations, 5 candidate dissertations, 4 specialists dissertations, 2 masters dissertations, 11 bachelors dissertations have been defended.
  • We have developed and implemented 3 lecture courses at MEPhI for masters: «Modern Astroparticle Physics» (David Besson), «Astroparticle Physics in Antarctica» (David Besson), «Using detectors with silicon photomultipliers» (E. V.Popova).
  • We have developed and implemented the «Measuring main parameters of silicon photomultipliers» case study into the «Using detectors with silicon photomultipliers» course.

Other results:

  • 6 intellectual property objects have been registered.
  • We have received 10 grants.
  • 4 contracts have been completed.


  • Pulsar (Russia): joint research, developing a technology for producing silicon photomultipliers based on CMOS and a special technology
  • Research and Production Complex «Technology Center» (Russia): producing silicon photomultipliers with record high efficiency in terms of latency
  • DESY (Germany):joint research, scientific seminars, student exchanges. For the first time we have compared characteristics of hadronic rains in multi-layer high granularity calorimeters with identical active elements but different absorbers and shown correlation of characteristics of reins with characteristics of materials. We have analyzed results of testing scintillator hadron calorimeter based on SiPM produced by the MEPhI team with a steel and wolfram absorbers and negative pions with energies ranging from 10 to 80 GeV
  • CERN (Switzerland): joint research, scientific seminars, student exchange. Participation in modernizing and calibration of centnral and rear parts of the CMS experiment hadron calorimeter. We have developed and tuned software for computing correction rates that allowed to conduct calibration in the presence of high level of event overlapping and to monitor response of the calorimeter during data accumulation. The performed calibration allowed to reduce variance of response to 1% depending on pseudorapidity both in the central and the rear part of a hadron calorimeter. Developed software modules are included into the CMS experiment software while correction rate obtained from experimental data from 2017 at 13 TeV energy have been submitted to the database
  • KEK (Japan): joint research. The Belle detector designed for researching disruptions of SR symmetry has been equipped with a powerful system consisting of 16.5 thousand scintillators with reading into SiPM. We have developed and programmed two types of space triggers: internal that uses information only from the KLM detector and external that selects events with passage of space muons through central flotation chamber. We have accumulated data of space sessions using these triggers and assessed efficiency of space muon passage detector
