Plasma Grid Cathodes Based on a Constricted Arc Discharge for Generating a Pulsed Intense Low-Energy Electron Beam in a Plasma-Filled Diode with a Longitudinal Magnetic Field

Abstract

Designs are presented for plasma grid cathodes based on an arc contracted discharge. They are designed to work under conditions of an inhomogeneous magnetic field as high as 35 mT and penetrate into their gas-discharge system from the region of electron beam transport. Parameters are presented of the electronic source used to modify the surfaces of materials and products using a pulsed electron beam in order to alter their operating properties.
