| 摘 要： | 首次实现直流磁体W波段二次谐波回旋管连续波稳定运行。回旋管工作时所需1.8 T磁场由一个水冷直流线圈产生。直流线圈励磁电流为500 A，功耗28 kW，内孔直径66 mm，可直接将回旋管插入内孔中。回旋管内电子束由双阳极磁控注入电子枪产生。采用高效率内置准光模式变换器实现束波分离并输出准高斯波束。研制的回旋管工作频率为94.08 GHz，腔内工作模式为TE02。实验中成功实现5 min连续稳定运行，输出功率达到12 kW。电子束电压为45 kV，电流1.7 A，对应的输出效率15.7 %。

| Abstract: | The continuous operation of a W-band gyrotron without superconduct magnet was realized. The gyrotron operated at the second harmonic cyclotron frequency. Its operational frequency was 94.08 GHz and the operating mode was TE02. The required 1.8 T magnetic field was generated by a DC solenoid cooled by water. The power consumption of the solenoid was 28 kW and the driving current was 500 A. The inner bore diameter was 66 mm. The gyrating electron beam was generated by a triode magnetic injection gun. A high efficiency internal quasi-optical mode converter was used to separate the wave from the electron beam. In the test, 5 min stable operation was realized. The output power was 12 kW with an electron beam of 45 kV, 1.7 A. The output efficiency was 15.7%. |
