Abstract

Summary form only given. The relativistic klystron is a strong candidate for a high power microwave source for a number of applications, including accelerators and electronic warfare. In this work, we simulate a high power, high perveance relativistic klystron oscillator using a 2d PIC-MCC code. The experimental klystron is currently operating as an injection-locked oscillator at 1.25-1.35 GHz, with up to 1 GW rms output power for a 100 ns pulse. The beam voltage is 500 kV, with current of 10 kA, and a beam pulse length of 300 ns. Experimental evidence indicates the klystron behavior is azimuthally symmetric.
