The results of numerical modeling of the proton accelerator channel in the most complex, from the point of view of acceleration and focusing of the high-current beam, energy range from the injection energy to 90...100 MeV are given. The stability of the movement of charged particles is ensured by a combination of modified Alternating Phase Focusing (APF) with magnetic focusing. It was found that the radiation purity of the accelerator, with a combination of modified APF with a spatially combined longitudinal magnetic field for an accelerated current of the order of 30 mA, is possible with a magnetic induction value of at least 1.9 T. It is shown that in the case of using permanent magnets, the necessary focusing stiffness is achieved by combining spatially combined modified APF and focusing by a magnetic field of a quadrupole configuration. Experimental data on the cross sections of nuclear fission reactions of heavy metals 197Au, 207Pb, 209Bi, 232Th, 238U when irradiated with protons with an energy of 0.66 GeV, as well as heavy metals 181Ta, 197Au, 207Pb, 209Bi, 232Th, 238U when irradiated with deuterons with energies of 2 , 2.94, 3.5 GeV/nucleon. The obtained results will be added to the international databases used in calculating the parameters of ADS systems. Deflection of a relativistic electron beam using a pyroelectric deflector was experimentally demonstrated for the first time. The possibility of using sequentially installed pyroelectric deflectors in a pyroelectric undulator to obtain undulator radiation by a relativistic electron beam without an external high-voltage power source is discussed.
