The main scientific results are as follows: a research bench has been developed to study PG parameters. The values of discharge currents of 7…25 kA at a voltage of 12…21 kV were obtained. The operation of PGs with different dielectric inserts, including ferroelectric (plumbum zirconate titanate, PZT), is considered. For PGs with use of PZT, the I-V characteristics in the voltage range of 12…21 kV were obtained, which have linear behavior. It is found that there is no delay between the operation of the main discharger and the discharger for that type PGs. Optical spectrogram showed that hydrogen and carbon were the dominating plasma components. After the discharge the PG traces on the titanium target were obtained, and the component composition of the deposited layer was determined. Copper, zirconium, titanium, plumbum and stainless steel components related to the chamber walls were found. Experiments on the discharge of different type gases puffing into the discharge gap of the laboratory bench, where the Penning discharge is used as a plasma source, showed that plasma in argon has the most stable temporal characteristics of plasma formation and lifetime compared to the one in nitrogen and carbon dioxide. For the development of plasma SNF processing methods, calculations on spatial separation for ions of a given mass range (M = 232...277) in a demonstration - imitation separator at the first turn of the ion trajectory, achieved by setting the amplitude and frequency of the variable component of a radial electric field in magnetic field of a given configuration.
