Abstract
An electron beam with current density greater than 30 A/cm2 and total current of 92 A has been generated in 5 μs pulses by accelerating the electrons from a glow discharge in a narrow gap between two grids. The ratio of the extracted electron beam current to discharge current is approximately 1. The gun also operates in a dc mode.
