Plasma electron emitter stabilized by a grid. I
Abstract
It is shown that if accelerated electron beams are to be obtained from plasma emitters, the beam current must grow quite slowly as the accelerating voltage increases. The basic types of plasma emitters are analyzed, and criteria are developed for assessing their performance under Knudsen conditions. A theoretical model is suggested in which the emitter is stabilized by a grid, and numerical calculations are carried out for a laboratory emitter.
