Relativistic electron beam injector synthesis on basis of geometrized space-charge-flow equations

Abstract

Algorithms and program of relativistic electron beam (REB) synthesis in the electrostatic compressor based on using of geometrized tubular relativistic beam equations are submitted. The calculations have confirmed efficiency of the algorithms, used in the program, and opportunity of high exit specific power injector creation with the help of the electrostatic compression.

Effect of space charge and the initial electron velocity on the potential distribution in a plane diode

“…In some of the subsequent publications, the velocity distribution was disregarded and it was assumed that electrons leave the cathode at the same velocity, which is either zero [8] or takes a certain finite value [4,5,9,10]. In these publications, it was addi tionally assumed that the diode operates in the regime of space charge limited current, in which the electric field strength at the cathode is zero.…”
