摘要：

A development of 170GHz/500kW level gyrotron was carried out as R&D work of ITER. The oscillation mode is TE31,8. In a short pulse experiment, the maximum power of 750kW was achieved at 85kV/40A. The efficiency was 22%. In the depressed collector operation, 500kW/36%/50ms was obtained. The maximum efficiency of 40% was obtained at P-RF=470kW whereas the power decrease by the electron trapping was observed. Pulse extension was done up to 10s at P-RF=170kW with the depressed collector operation. The power was limited by the temperature increase of the output window.
