Abstract

Design and experimental studies of the 120 GHz, TE03 mode gyrotron of Mitsubishi Electric Corp. are reported. Since the first operation of our 120 GHz, TE03 mode gyrotron (1), our efforts have been aimed at increasing an output power on the second tube. The second tube is a modular type and allows interchange of important parts such as a magnetron injection gun, a cavity and a window. The tube with a nonlaminor gun and a simple tapered cavity (Q=579) has achieved the maximum output power of 167 kW at 120 GHz in the TE03 mode with short pulse. The efforts for increasing pulse width have been also continued. A 150 kW, 10 msec, sealed type of gyrotron was reported at the 5th Annual Conference of the Japan Society of Plasma Science and Nuclear Fusion Research (March, 1988). In this paper, most part is devoted to descriptions of short pulse operation on the second tube. The rest introduces the design of a complex cavity for high power (~200kW) and long pulse (~100ms) gyrotrons.
