Methods of high-temperature (400…1300°С) experimental irradiation tests of accelerated electrons and helium ions irradiation enhanced thermodestruction of carbonaceous materials in an oxidizing medium were developed along with the tune-up of the dedicated experimental stands equipment. Self-consistent equations of the helical electron beam e.-m. interaction in a sub-terahertz gyrotron coaxial resonator having the insert with distributed longitudinal corrugations were derived; the insert optimal structure was found by evaluation of its effective surface impedance and the competing modes starting currents. New algorithms and spectral synthesis generators of models of materials with scale-invariant fractal mesostructure were introduced into the Monte Carlo code RaT; stochastic effects of non-classical radiation transfer and the influence of their fractal dimension on the neutron and gamma-irradiation dosimetry were revealed. The phenomenon of coherent dispersionless transport of particles ensemble in underdamped systems with sloped periodic potentials was critically analyzed by means of the developed physical model and code for defects and impurities diffusion motion simulation in spatial lattices under fixed external force. Based on the developed models of convective mass transfer in viscous incompressible media heated from below in external magnetic fields and temperature gradients, the process of vacuum-arc remelting of innovation steel was optimized and the experimental data on supercritical carbon dioxide fluid extraction of heavy metals isotopes were explained. The design of a vacuum filter for handling with the thermal-vacuum process obtained nanodispersed materials was developed and prepared for patenting.
