Abstract

Gyrotron is the heart of the ECH system for heating and current drive of tokamak fusion reactor. Recent progress of the gyrotron development in Japan (JAERI/Toshiba), Russia (Gycom) and USA (Varian) initiated the 170GHZ, 1MW, CW high efficiency gyrotron development for ITER. Key technologies of the high efficiency, high power, long pulse gyrotron development are described. The energy recovery gyrotron which recently achieved 50% efficiency in JAERI is mainly described as an example of the development.
