Feasibility study of the EU home team on a 170 GHz 1 MW CW gyrotron for ECH on ITERFunded under: EAEC-FUSION 12C
The gyrotron system for ECH and burn control on ITER requires at least 50 MW of RF power at frequencies near 170 GHz operating in CW. To meet these requirements, high efficiency gyrotron tubes with power output capability of the order of 1 MW are necessary, as well as simple coupling to either a quasi-optical or waveguide transmission line. The paper reports a feasibility study on the design of an ITER-relevant gyrotron oscillator at 170 GHz, 1 MW CW employing a diode electron gun, an advanced internal quasi-optical converter, a cryogenically cooled single disk sapphire window, and a depressed potential collector. The operating mode selection and the cavity design are a compromise between many design constraints.
