Abstract

Summary form only given. We present the preliminary design of a high power amplifier with a metamaterial interaction cavity. The amplifier will operate in the S-band (3 GHz) frequency range with a peak power of 10 MW. The amplifier will utilize a 500 kV 80 A electron gun, which has been simulated using the code MICHELLE. Simulations of the gun and other major amplifier components are also discussed. Details of the various components in the amplifier design as well as the interaction cavity itself are presented. In addition, EM field and particle simulations of the interaction circuit are presented. The differences between the integration of a metamaterial interaction cavity and a traditional cavity are discussed.
