Electron beam generated in a vacuum diode of the pulsed accelerator based on an inductive energy storage device with a plasma opening switch. The materials are treated with an electron beam. The purpose of the work – the calculation of the maximum density of plasma needed to neutralize the positive volume charge of ions and the topography of the magnetic field for the existing magneto-plasma separator in order to increase its productivity. Determination of the effect of an additional solenoid with a reverse magnetic field, located on the axis of the vacuum chamber, on increasing the efficiency of the spent nuclear fuel separation process. Study of the effect of nanosecond pulses of a high-current electron beam on materials with oxide coatings, pure metals, their alloys and polymers, with the aim of improving their technological properties. The main scientific results are as follows: -for the first time, the dimensions and parameters of the magnetic systems of the plasma source and the magneto-plasma separator were calculated for creating an ion flow of light metal oxides (simulators of spent nuclear fuel) and their separation; - for the first time, a direct-action accelerator with an inductive energy storage with a plasma opening switch was used for investigating the influence of the pulsed high-current electron-beam treatment of nanosecond duration on the properties of the surfaces of metals, alloys, metals with oxide coatings and composite polymers. An increase in microhardness and removal of surface tension of the surfaces of stainless steel samples was obtained.
