Main motivation of the high power gyrotron is the application to the plasma heating and current drive and control of the magnetic confinement fusion devices. Using a multi-frequency operation, 1 MW Gaussian beam output was obtained at four frequencies; 203 GHz  (TE37,13), 170 GHz  (TE31,11), 137 GHz (TE25,9), 104 GHz (TE19,7). In particular, the achievement of 203 GHz 1 MW output at 50 % will give a strong impact on the DEMO (Demonstration power plant) design. In parallel, a high frequency oscillation up to 300 GHz was studied using a short pulse gyrotron under collaboration with University of Tsukuba. In this gyrotron, 300 GHz/ 0.6 MW (TE31,18), 240 GHz/ 0.35 MW (TE28,14) oscillations were demonstrated.
