The aim of the project is to research, develop and optimize linear ion accelerators based on alternating phase focusing and H-resonators for power engineering, nuclear physics and radiation technologies, investigaton and application of transient, parametric and characteristic X-ray radiation for diagnostics of charged particles beams, as well as study direct-action charged particle accelerators based on ferroelectrics for controlled miniature ionizing radiations sources.

 The results of the helium ion accelerator (POS-4, ion energy 4 MeV, beam current up to 1 mA) modernization, which is used for research in radiation materials science, are presented. The chamber for irradiating samples of structural metals and ceramics was modernized, which allowed to expand the range of temperature regimes during irradiation. The power supply systems of the helium ion injector were properly developed, the plasma ion source and the vacuum system of the injector were reconstructed, and a new high-voltage electrostatic tube was manufactured. As a result, a new injector with higher stability and productivity was put into operation. A radiation-clean accelerating and focusing channel for a proton beam with a current of 50 mA to an energy of 150 MeV was developed using the method of numerical modeling, in which the stability of particle motion is ensured by spatially combined alternating-phase magnetic quadrupole focusing. The Monte Carlo method was used to simulate the irradiation of a quasi-infinite uranium target with protons and deuterons with energies up to 10 GeV. The spectra of secondary particles in the target were obtained, and the number of reactions 235U(n,f), 238U(n,f) occurring in the target during irradiation with protons and deuterons was calculated. The beam power gain coefficients were determined. A new method was developed for experimental study of the dechanneling phenomenon and obtaining information about the dynamics of charged particles in crystals. The method is based on measuring the ionization loss spectra of charged particles channeled in a semiconductor crystal detector – a target with a smoothly varying thickness of the depleted layer.
