“…The EDA phase (engineering design activities) of a 170 Hz gyrotron was carried out by Europe, Russia and Japan for a long time [3][4][5]. Before the 2000s, the high-power long-pulse gyrotron underwent important breakthrough technology, such as improving the efficiency of mode converter [6,7], designing a depressed collector [8,9], and upgrading the window material to diamond [4,10], thus realizing the technology route of the 170 GHz, 1 MW CW gyrotron. The Beijing Vacuum Electronics Research Institute (BVERI) designed a 170 GHz gyrotron, aiming to satisfy the basic performance requirement of the EAST gyrotron.…”

This paper presents the overall conceptual design of a 170 GHz, 1 MW gyrotron for plasma heating applications in thermonuclear fusion reactors. The operating mode is carefully selected with consideration of mode competition. The TE25,10 mode is determined as the operating mode in the present study. A weakly tapered conventional resonator is used for the study of the RF behavior, and multimode calculations are carried out for power and efficiencies. The optimized structure of the beam tunnel can further attenuate low-frequency oscillation. The design studies of a triode-type magnetic injection gun, quasi-optical mode converter, and single-disc sapphire window are also described. In addition, novel cold test methods which can effectively validate assembles are designed. In 2021, a prototype gyrotron was fabricated to validate the electronic–optic system and RF system. The current results obtained support an output power of 210 kW and efficiency of 15.9% through an initial low-power experiment. On the basis of the optimized design, an industrial prototype gyrotron is under fabrication as the heating source for the thermonuclear experimental reactor.
