Features of Electron Optical Systems with the Plasma Emitter Based on Stationary Double Electric Layers in the Plasma

Abstract

The physical concept and the model of the construction of the plasma source of charged particles in crossed E × H fields are presented in which, due to the special configuration of the electrode structure, conditions are created for the formation of stationary double electric layers. It is shown that the formation of such layers promotes the growth of the source perveance and provides the possibility of simultaneous or alternating formation of flows of charged particles of different signs. The electrode structure and the main characteristics of the developed source are given, and the mechanism of its operation is proposed.
