Laboratory of Cyclotron and Fast Neutron Generators (LC & FNG)

The cyclotron TR-24


The cyclotron TR-24 provides proton beams with energies from 18 MeV to 24 MeV and currents up to 300 μA. In connection with the developed target stations the beams are mainly used for the production of high fluxes of fast neutrons based on the p+Be source reaction, production of the calibration sources and tracers and production of conventional and nonconventional medical radionuclides.

The isochronous cyclotron U-120M

The isochronous cyclotron U-120M is a versatile machine operated both in positive and negative modes. It can accelerate light ions (H+, H, D+, D,3He+2, 4He+2) in the energy range from 1 to 55 MeV. Positive ions (H+, D+, 3He+2, 4He+2) are extracted from the cyclotron by means of three sections electrostatic deflection system with a magnetic kicker. Negative ions H, D are extracted by a stripping method using a thin carbon foil. A set of high-power broad-spectrum and quasi-monoenergetic neutron fields at energies up to 35 MeV are produced using ion-beam reactions on special neutron source targets.

Basic and Applied Research with Ion and Neutron Beams

Due to variability of accelerating regimes, complementary optical beam lines with diagnostics and variety of target stations and irradiation facilities, the cyclotron is an efficient tool for various basic and applied research experiments. One of the unique facilities is the high-power p-D2O fast neutron source. Together with other variable-energy neutron sources and irradiation chambers, these facilities are operated for validation of fusion relevant nuclear databases and for various non-power applications. Accelerated ion beams can be provided for measurement and validation of data for nuclear astrophysics, excitation functions measurement and production of radionuclides for research. Moreover, accelerated ion beams can be adapted and provided for other applications like ion-beam irradiations of various samples and materials under vacuum or in air after beam extraction through vacuum window (i.e., material modification with ion beams, material modification studies, irradiations of biological samples, semicontrolled device testing under specific irradiation conditions etc.).
