Novel Semiconductor Detectors for Fundamental and Applied Research
| Leader: | G.A. Shelkov |
| Deputy: | A.S. Zhemchugov |
Participating countries and international organizations:
Belarus, CERN, Cuba, Croatia, Czech Republic, Germany, Italy, New Zealand, Romania, Russia, South Africa, Switzerland, United Kingdom, USA.
Issues addressed and main goals of research:
development of the existing scientific and technical base for R\&D of semiconductor radiation-resistant detectors and hybrid high-resolution pixel detectors based on new semiconductor materials and Medipix readout chips for physical studies. development of the existing infrastructure for characterization of semiconductor detectors created at JINR and laboratories of the participating countries, in conjunction with beam tests at the JINR basic facilities. Conducting joint investigations in collaboration with research groups from other scientific centers to determine the potential of using the developed detectors and technologies in other fields of science and technology, especially in geology and biomedicine.
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.
Development and construction of setups for experiments at accelerators for obtaining new information and testing the present theoretical views in the strong, weak and electromagnetic interactions of elementary particles and light nuclei at intermediate energies with the aim of determining symmetries and dynamics of the interaction.
Expected major results in the current year:
- Data taking and analyze the information from GaAsPix system for radiation background monitoring in ATLAS.
- Study of the radiation hardness of GaAs:Cr.
- Measurement response of Timepix detectors and development the method of particle identification.
- Upgrade of the existing stations for measuring properties of semiconductor detectors.
- Installation in a MARS microtomograph pixel detector with larger size and magnification.
- Construction microtomograph with a fixed large area detector and a rotating specimen.
- Development of a full-featured readout electronics unit for Timepix and preparation for the creation of detectors based on the Medipix4 chip.
- Development of methods for spectral microtomography, including the improvement of computational algorithms.
- CT scan bio samples in cooperation with medicine expert.
- Studies of the possibility of isolating radiopaque substances in the body according to the energy dependence of the linear attenuation coefficient.
- CT scan of ores and mineral raw materials in cooperation with geophysicist.
- Creation a test version of the device forming an orderly flux of positrons.
- Experiments with the Active Target (GDH).
