More Information
Summary:The results of computer simulation and full-scale modeling of gas flows injected into the plasma focus chamber using a high-speed valve (200–300 microseconds) are presented. The purpose of the work being carried out is to expand the possibility of matching plasma focus installations with an increase of discharge currents to values above 2–3 MA with the initial formation of a plasma current shell in heavy inert gases. The results of the analysis are compared with data from a series of electric discharge experiments made with a helium current shell compressing a localized region with injected deuterium.
