  • The high frequency characteristics and beam-wave interaction system with four cavities in the Ka-band sheet beam relativistic klystron amplifier were simulated with three-dimension electromagnetic codes. The simulation results show that for a 500 kV, 1 kA, 40∶1 aspect ratio sheet beam and 1.94 kW input power with 0.8 T leading magnetic field, the sheet beam klystron is capable of generating an output power higher than 142 MW at 40 GHz with a gain of 48.6 dB and a maximum efficiency of 28.4% at a frequency of 40 GHz.
