Microplasma oxidation of the materials surfaces is expected to carry out in order to improve the characteristics of materials’ for plasma and accelerator technology. Research of ion separation in a multicomponent plasma rotating in the crossed magnetic and electric fields is supposed to be carried out for simulation of nuclear fuel separation from spent nuclear fuel in a closed nuclear fuel cycle by plasma methods. popup.description2 The object of the investigation - coaxial plasma source of electroerosion type. Crossed magnetic and electric fields of the DIS-1 separator, which ensure the rotation of ions along certain trajectories and their collection on the extension and end collectors. Plasma rotating in crossed electric and magnetic fields and source materials deposited on the collectors. Induced voltage, current and electromagnetic radiation on the DIN-2K accelerator. The purpose of the work – ensuring the formation of plasma, which are components of the structural materials of nuclear reactors, in particular Zr, ZrO2, Ti, Nb, W. Creation and calculation of crossed magnetic and electric fields, which will ensure the propagation of ions along given trajectories and their collection on collector targets. Creation of interference-resistant conditions for diagnostics of electromagnetic radiation on the DIN-2K accelerator. Development of a method for determining directional diagrams. Determination of parameters of electrical circuits that provide maximum multiplication factors of the discharge voltage. The main scientific results are as follows: - For the first time pulsed plasma sources based on Ti–Zr–ZrO₂ and W–ZrO₂–Nb were created. It was proven that the selected combinations of materials (W, Nb, Zr, O) and discharge modes ensure the formation of multicomponent metal-oxide plasma with masses representative of refractory components of spent nuclear fuel and structural materials of heat-generating assemblies and controlled directing of ions to a specially designed system of longitudinal and end collectors; - For the first time, a method for determining the directivity pattern of short-term, up to 100 ns, pulsed electromagnetic radiation has been developed using a semiconductor power sensor.
