Abstract

A 28 GHz/35 GHz dual-frequency gyrotron has been developed for use by the University of Tsukuba and its collaborative research institutions. This gyrotron incorporates a sapphire double disk window for 28-GHz 0.4 MW-Continuous Wave (CW) operation. The heat transfer coefficient was estimated by comparing the measurement results of the output window temperature with calculated values and the results suggest that this gyrotron can operate in the CW operation.
