A theoretical and experimental analysis of the large-signal behavior of distributed klystrons

This paper describes theoretical and experimental studies of the behavior of standing-wave type distributed interaction klystrons. The theoretical study was based on a confined flow disc electron computer analysis which can predict the klystron conversion efficiency within a few percent. The computer analysis takes account of space charge forces, provides a self-consistent check on the beam and circuit power flow and also can predict the conversion efficiency for any kind of distributed cavities with a standing-wave field distribution.
