Abstract

The progress of the 105/140 GHz MW gyrotron experiment aiming for fusion application is presented. The gyrotron employs dual-frequency design in triode magnetron injection gun, cavity, quasi-optical mode converter and window. In the experiment, pulse power of 710 kW at 105 GHz and 1.057 MW at 140 GHz were achieved at 1 Hz repetitive rate. The total efficiency is 34% and 49%, respectively. The experiment has firstly demonstrated the MW-level power output in the domestic quasi-optical gyrotron tests.
