Abstract

A highly overmoded 85 GHz gyroklystron experiment is reported using two quasioptical resonators. Phase locking at 70 kW output power and 16% efficiency is demonstrated over the entire linewidth of the output resonator by prebunching the electron beam. Amplifier operation at 30 kW output power is observed with over 18 dB gain. Two techniques, mode priming and alpha priming, allow access to the hard excitation region of the gyroklystron. Good agreement is obtained between the multimode simulation code and important features of the experiment.
