Paper Abstract

Axisymmetric simulation codes have been extensively used to model relativistic klystron amplifier (RKA) devices. However, the inductively loaded wide gap cavity, which has been reported by Friedman, et al. and Serlin, et al. (these proceedings) contains several axial rods in the gap and thus is inherently nonaxisymmetric. An external circuit model has been incorporated into the axisymmetric simulation code MASK to treat the inductive structure. The structure is intended to allow much higher dc currents to propagate without the formation of a virtual cathode while allowing rf fields to penetrate. Simulation results confirm this picture and are in good agreement with preliminary experiments.
