Paper Abstract

We present results of simulation studies of several novel RKA configurations each of which is designed to increase the amplification of the stimulated beam modulation. The main configuration under consideration is the two-beam RKA. Results presented here, in which the two beams have the same injection energy, do not show any increase in modulation over a single-beam RKA, even when the total beam current is close to the limiting current. Summarized are simulation studies of several novel RKA configurations, including the two- beam RKA and the sequential interaction of a single-beam RKA with a chain of passive cavities. We have also examined the interaction of an intense beam with a corrugated slow- wave structure that is contemplated for RF extraction. Other areas of research include the effect of a resistive wire inside the coaxial RKA near the beam formation region to damp unwanted TEM or TM modes and some relativistic klystron oscillator (RKO) configurations.
