The initial conditions were varied by changing the type of working gas and the initial pressure in the vacuum chamber. The initial conditions were chosen in such a way as to keep constant the integrated consumption of working gas. Only the initial concentration of the working gas changed.It has been shown experimentally that the magnitude of the plasma density in the compression zone, its spatial distribution significantly depend on the initial concentration of the working gas. In addition, as the initial concentration decreases, the compression zone moves away from the Central electrode, and its linear dimensions increase. The duration of plasma flow generation also increases by 1.5-2 times when the initial concentration is reduced by half.In the plasma flow, the formation of toroidal current vortices and the displacement of current from the axial region, where the compression region is formed. It is important to note that the area where the current displacement is observed increases with decreasing initial concentration.The ion-optical system was modernized and a neutralizer with software control of sodium vapor supply time in the neutralization area for PES plasma diagnostics on a Hurricane-2M torsatron was manufactured and tested. The new ion-optical system is equipped with modified units and software and allows to operate with ion beams in a wide range of beam currents from 0.5 to 3.5 mA and their diameters from 8 to 30 mm with beam energy up to 25 keV. Test tests of the new neutralizer system showed the reliability of its elements and the possibility of obtaining the neutralization coefficient of sodium ions up to 96%.The technology of strengthening of piston rings by a multilayer ion-plasma covering of TiN / CrN at application of an arc plasma source is offered.  Product Description popup.authors Yeliseev Dmytro V.
