3. Spectroscopy of gamma radiation

A set of laboratory works on gamma-ray spectroscopy was developed at the International Department of Nuclear Physics, New Materials and Technologies. The complex includes the experimental plant "GAMMA-RAD5" (shown in the figure), which makes it possible to carry out experiments to study the interaction of high-energy gamma radiation with matter, as well as detecting and measuring the background of gamma radiation. Due to the peculiarities of the "GAMMA-RAD5" spectrometer construction, the whole process can be controlled by the computer to which the plant is connected. The spectrometer scintillator is wear-resistant to mechanical influences and vibrations. In addition, the device is connected via an Ethernet connection, allowing various manipulations at distances up to 100 m, or using a single USB connection for almost any computer. Finally, it has a flexible architecture that makes it possible to adapt easily the plant for specific tasks.

4. Laboratory of Cosmic Rays

On the basis of the International Department of Nuclear Physics, New Materials and Technologies, the Laboratory for Cosmic Ray Physics was created to measure and process helio and geophysical parameters (monitoring radiation and electromagnetic conditions). A ground-based complex of equipment has been created, including an installation for recording soft (electron-photon) and rigid (muon) components of cosmic rays. It is supposed to include a measuring instrument of electrophysical fields in the complex of ground-based instruments.

The experimental data obtained with the help of the ground complex will make it possible to carry out long-term research on such world fundamental problems of cosmophysics as:

1) Processes of acceleration of charged particles in such astrophysical objects as supernovae, the study of processes taking place on the Sun (solar flares), the propagation of cosmic rays in the near-Earth space and the magnetosphere;

2) Mechanisms and sources of modulation of cosmic ray fluxes in the interplanetary medium and heliosphere;

3) The physical role of charged particle fluxes in the terrestrial atmosphere, in global atmospheric processes (thunderstorm activity, global electrical circuit, global warming process);

4) "Space weather" on the Earth, as well as solving a number of applied problems;

5) Investigation of radiation and ionizing fields and their dynamics in the surface layer.

The laboratory uses the cosmic ray detector CARPET; they are designed for continuous monitoring of the cosmic ray flux at the Earth level.
