Tilted Resonator Experiments on a Quasioptical Gyrotron.

Abstract

Tilting the resonator axis slightly with respect to the magnetic field axis in the quasioptical gyrotron (QOG) is predicted to greatly enlarge the parameter space available for stable, single-mode operation. Greater interaction efficiency is also predicted for single-mode operation. A resonator with a 2 degree tilt has been tested on the QOG experiment. The operation of this resonator has been compared to an untilted, but otherwise identical resonator. Multimode operation of the two resonators was very similar, in contrast to predictions. However, an output power of 600 kW was produced at an efficiency of 8% and a frequency of 120 GHz. At lower power, efficiencies above 12% were observed. The efficiency of single-mode operation appears to be raised significantly by tilting the resonator axis.
