Abstract :
The feasibility of an 84 GHz, 500 kW, CW gyrotron for ECRH on an experimental tokamak is presented in the design study of this paper. Mode competition and mode selection procedures are carefully investigated by considering various candidate modes and the TE10,4 mode is chosen as the operating mode. A suitable cold cavity is considered with quality factor around 1000. Self-consistent calculations are carried out and power and efficiencies are computed for a typical set of beam parameters. The results show that an output power of well over 500 kW, CW and efficiency around 40% can be reached without a depressed collector.
