Abstract

An analysis has been carried out for the generation of high density and energetic electron beam in the pseudospark discharge based plasma cathode electron (PD-PCE) source. The study of a-beam generation and propagation has been performed for single as well as multi-gap arrangement of PD-PCE source using 2-U PIC simulation code, and also experimentally at different operating and geometrical parameters. The investigations clearly show that the cathode aperture, gas pressure and seed electron energy are some of the important parameters strongly affecting the generation of pseudospark discharge based high density and energetic electron beam generation. The PIC simulation and experimental investigation of different configuration of PD-PCE source would be utilized for the generation of efficient plasma generation inside the hollow cathode cavity and hence electron beam for different geometrical sizes and operating parameters
