内容記述 |
This paper presents the achievement of development of megawatt-power gyrotrons and the gyrotron control techniques at QST. We have newly developed a multi-frequency gyrotron capable of oscillating at three frequencies, 170 GHz, 137 GHz and 104 GHz, to aim to enable plasma heating and current drive at wide magnetic field strengths from 1.8 T to 5.3 T at the ITER. This gyrotron demonstrated 300 s continuous operations with the output power of 1 MW at 170 GHz and 137 GHz, 0.9 MW at 104 GHz. These performances by one gyrotron are the first achievement in the world. We have established two sophisticated heater-power control schemes to realize flexible and stable operation of the gyrotron. Real-time stabilization of the beam current was successfully achieved and a long-pulse operation of 1 MW, which is combined with steady operation and 5 kHz modulation operation was demonstrated. |
