摘要

兆瓦级回旋管是磁约束核聚变系统ECRH中的关键器件。为了实现CFETR所采用的170GHz回旋管的高功率和长脉冲，本文进行了te25.10模式170GHz回旋管的研究。利用PIC对单阳极磁控管注射枪(MIG)和圆柱形谐振腔的工作方式进行了设计和优化。在工作电压75kV、电子电流45A的条件下，回旋管的理论输出功率约为1.1MW，对应电子效率为32.6%。利用单抑制集电极和准光模式变换器制作了回旋管，并将在未来进行测试。

Study of long-pluse high-power 170GHz gyrotron for fusion plasma ECRH

The MW gyrotrons are key devices in ECRH of magnetic confinement nuclear fusion systems. In order to achieve the high power and long pulse of the 170GHz gyrotron, which are adopted in the CFETR, a TE25.10-mode 170GHz gyrotron research are given in this paper. A single-anode magnetron injection gun (MIG) and the cylindrical resonant cavity operating are designed and optimized by PIC. The theoretical output power of the gyrotron with operating Voltage 75kV, electron current 45A is about 1.1MW, corresponding to electron efficiency of 32.6%. The gyrotron has been fabricated with the single-depressed collector and quasi-optical mode converter and will be tested in the future.
