The electron beam current of high-power, long-pulse gyrotrons for fusion devices is typically controlled to remain constant by adjusting the power to the cathode heater by using a pre-programmed waveform. However, this pre-programmed waveform is usua

High-power (1 MW), long-pulse operations up to 300 s were demonstrated by multi-frequency oscillations at 170 GHz, 137 GHz, and 104 GHz. A multi-frequency gyrotron based on the design of the ITER gyrotron has been developed and studied. By redesignin
