Issues addressed and main goals of research:
Development of the existing scientific and technical basis 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. Conduct of 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.
Upgrade of the electron accelerator Linac-200 up to 800 MeV and creating of a research infrastructure for studies using its test beams. Use of the facility for applied research and practical training of students and PhD students - future engineers from the JINR member states.
Research in condensed matter physics using the method of positron annihilation spectroscopy (PAS). Development of a PAS method based on the beam of monochromatic positrons, and 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.
