Abstract :
Recent progress of JAEA high power long pulse gyrotron is reported. Multi-frequency oscillations and their Gaussian beam outputs are demonstrated at 170 GHz, 137 GHz and 104 GHz. For the full power modulation, clear 5kHz modulation was demonstrated using double anode switching. Furthermore, novel anode power supply system was fabricated to simplify the gyrotron power supply system.
