| 内容記述 | Multi-frequency Mega Watt-class gyrotrons have being developed for ITER and JT-60 SA project in QST. Stable operation of 170 GHz oscillation with higher total efficiency were achieved in ITER gyrotron with high-order volume mode of TE31,11 mode by introducing active anode voltage control and beam radius control to suppress adjacent counter-rotating modes. In long pulse operation, 1.0 MW/46 % for 300 s was achieved and 1.2 MW was obtained until 5 s. In multi-frequency oscillations, experiments of 203 GHz oscillation for a demo-reactor grade were started and the output power of 0.9 MW in short pulse and 0.42 MW for 5 s were demonstrated as preliminary results For lower frequencies, 1.0 MW/6 s at 137 GHz, and 1 MW/2 s and 0.93 MW/5 s at 104 GHz were also achieved. The ITER gyrotron having mega-watt-class power at four frequencies in wide range over 100 GHz was developed. In the JT-60SA gyrotron, oscillations of 1 MW/100 s at both 110 and 138 GHz had been already achieved. Enhancement of maximum power was progressed and 1.9 MW/1 s at 110 GHz, which is a world record power in non-coaxial type gyrotron has been achieved. And high-power oscillation at 138 GHz (1.3 MW/1.3 s) and 82 GHz (1 MW/1 s) have been demonstrated as a new record. | |||||
