Abstract :
The design of a high power gyroklystron amplifier operating with circular TE011 cavity modes is presented. The amplifier will be driven by a 70-kV, 6-A electron beam with a pitch angle (vt/vz) of 1.4 and velocity spread of 2.4% generated by a double-anode magnetron injection gun (MIG). The amplifier is predicted by particle-in-cell simulation to generated 145 kW at 94.1GHz with 35% efficiency, 38-dB saturated gain and 0.8GHz bandwidth.
