Simulation of electron beam generation with a constant, rising and falling beam power during its pulse

Abstract

Abstract In this work, we simulated the operation of an electron source with a grid plasma cathode based on a low-pressure arc discharge, where a high-voltage capacitor bank of a given capacity is used to accelerate the beam electrons. Based on the unique ability of such electron sources to generate electron beams with parameters independent of each other, capable of being regulated within relatively wide limits, the calculations were carried out with the aim of producing an electron beam whose power can be controlled during a beam pulse of a millisecond duration when the beam power is constant or has a linear rise or fall. The calculations confirm the uniqueness of plasma electron sources and open up new possibilities for their use in scientific and technological purposes.
