摘要
研制出国内首支基于电子回旋加热应用的28GHz/50kW准光输出大功率连续波回旋管。该回旋管采用了双阳极磁控注入枪,TE02模式谐振腔,内置准光模式变换器,单级降压收集极。回旋管采用无液氦制冷超导磁体提供稳态磁场。实验中成功实现54.8kW/1s短脉冲输出和45.8kW/30s的连续波输出,工作频率为28.08GHz,总效率达到57%。
Aiming for electron cyclotron heating application in plasma fusion system,a 28 GHz 50 kW gyrotron has been developed and fabricated.The gyrotron employs a triode magnetron injection gun,a conventional cylindrical cavity working under TE 02 mode,a built-in quasi-optical mode converter with conversion efficiency of about 95%.In the experiment,Gaussian beams of 54.8 kW for 1 s pulse and 45.6 kW for 30 s continuous wave at 28.08 GHz were achieved.The corresponding total efficiency is 57%.
