Investigation of electron beam parameters inside the drift region of plasma cathode electron gun

TLDR: In this article, the authors present experimental studies for the production and propagation of an electron beam from a single gap pseudospark discharge based plasma cathode electron (PCE) gun, which has successfully propagated for more than 25 cm in a gaseous environment without application of external guiding magnetic field at different operating conditions.

Abstract: This paper presents experimental studies for the production and propagation of an electron beam from a single gap pseudospark discharge based plasma cathode electron (PCE) gun. The generated electron beam has been successfully propagated for more than 25 cm in a gaseous environment without application of external guiding magnetic field at different operating conditions. The electron beam losses due to recombination with ions and collision with walls of drift space have been estimated. The electron beam profile has also been analyzed in the drift region of the gun.
