Abstract

A high power submillimeter, harmonic gyrotron oscillator is currently being operated at M.I.T. To achieve second harmonic emission, three different cavity configurations were studied: a tapered cavity, a slotted cavity, and a cavity with an output iris. In the cavity containing an output iris, second harmonic emission was observed at 6 frequencies between 301 GHz to 373 GHz with output powers of 4-6 kW, and at 417 GHz with an output power of 15 kW. The latter measurement corresponds to a total efficiency of 6%. A variety of diagnostics capable of discriminating between fundamental and second harmonic emission were also investigated.
