Those RF beam passed through the center of the gyrotron window and good couples to transmission line were obtained for each oscillation. The mega-watt-class power was obtained for all frequencies. Validation of gyrotron for a demo reactor is numerically started on the basis of our multi-frequency gyrotron., 41st International Conference on Infrared, Millimeter and Terahertz Waves}, title = {Development of multi-frequency gyrotron for ITER and DEMO at QST}, year = {2016} }
