Paper Abstract

A prebunched beam has been used to further increase the efficiency of our axis-encircling high harmonic gyrotron. The experiment was performed at the third harmonic with a TE312 mode at 27.7 GHz. The conversion power was 6.7 kW which was significantly greater than that of a non-prebunched comparison experiment. Also, mode competition was substantially reduced. The dependence of the output power on the square of current has been verified. The start of oscillation current is effectively zero.
