Calculation of stationary electron beams with space-charge-limited current

Radiophysics and Quantum Electronics Aims and scope

Abstract

The calculation method is based on direct satisfaction of the condition of a zero normal electric field on the emitter by means of an iteration procedure that makes it unnecessary to obtain self-consistent solutions of the stationary-beam equations in individual iterations. The method employs auxiliary potential and space-charge nets for solution of the boundary-value problem and eliminates the idle nodes of the auxiliary potential net. The method is effective in the analysis of curvilinear beams and has been tested in the design of a Meltzer gun with circular trajectories and a strongly nonuniform transverse current distribution.
