Plasma Injectors for Quasi-Stationary High-Power Plasmodynamic Systems

Abstract

Pulsed plasma injectors, that is, an “input ionization chamber” (IIC), an “anode ionization chamber” (AIC), and a high-pressure plasma injector, are described. Plasma injectors are designed to generate primary plasma in quasi-stationary high-power plasmodynamic systems, in particular, in the KSPU Kh-50 quasi-stationary high-current plasma accelerator. The results of studies of the main characteristics of plasma pulsed injectors are presented. The following charge currents in plasma were obtained: 23.5 kA for the AIC injector at a voltage of 3 kV, 90 kA for the IIC injector at a voltage of 0.65 kV, and 96 kA for the high-pressure plasma injector at a voltage of 3 kV.
