Novel Semiconductor Detectors for Fundamental and Applied Research
| Leader: | G.A. Shelkov |
| Deputy: | A.S. Zhemchugov |
Participating Countries and International Organizations:
CERN, Czech Republic, Germany, New Zealand, Poland, Russia, South Africa, Ukraine.
Scientific Programme:
Generic R&D of semiconductor radiation-resistant detectors based on new materials and of hybrid pixel detectors with high resolution for nuclear and particle physics. Development of the research infrastructure for semiconductor detector R&D, coupled with beam tests at the JINR facilities, to be used by groups from JINR and from the Member States. Scientific collaboration with research groups from other fields in feasibility studies of application of the newly developed detectors in others areas of science and technology (primarily in medicine and geology). \\ Research in condensed matter physics using the method of positron annihilation spectroscopy (PAS). Development of a PAS method on the beam of monochromatic positrons, the creation of equipment for spectroscopy by the Doppler method of measuring the lifetime of positrons in matter.
Expected main results in 2017:
- Systematic studies of radiation hardness and response of GaAs detectors in the beams of the JINR
facilities.
- Production of prototypes of Timepix hybrid pixel detectors with GaAs sensor of thickness less
than 1 mm. Study of their capabilities in detecting neutrons, fission fragments and charged tracks.
- Production of a prototype of the low-background GaAs-based hybrid pixel detector for TGV-2.
- Study of X-ray contrast media identification by spectral data.
- MARS-CT calibration and image processing aimed at geophysics studies.
- Test of the block of registration for an electromagnetic calorimetry.
- Project preparation about use of new semiconductor photodetectors in a calorimetry for high energy physics.
- Commissioning of the slow monochromatic positrons cryogenic source, construction of the closed autonomous
cooling system and the emitter-source of the activity of 30 mCi.
- The construction and commissioning of the specialized monochromatic positron channel (SMPC) and the experimental station.
Start of research by Doppler method.
