Analysis of an inductive energy high-perveance electron-beam generator

Recently, Slivkov and Dolgachev [1] proposed an interesting type of electron-beam generator, consisting of a high-voltage triode in series with a storage inductor. During the storage time, the triode operates with a depressed collector voltage. A high-energy current pulse is obtained when the triode is switched from a high-perveance state to a low-perveance one. In this paper, the circuit model for the beam generator was expanded to take into account grid capacitance and beam loss. Computer results based on the new circuit model predict a train of sinusoidal-like pulses in the triode output when the grid is suddenly connected to a portion of the storage inductor. An electron-beam generator, capable of producing a train of megavolt pulses at high currents, is predicted.
