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1.8T磁场由一个水冷直流线圈产生。直流线圈励磁电流为500A,功耗28kW,内孔直径66mm,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94.08GHz,腔内工作模式为TE02。实验中成功实现5min连续稳定运行,输出功率达到12kW。电子束电压为45kV,电流1.7A,对应的输出效率15.7%。
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 was94.08GHz and the operating mode was TE02.The required1.8T magnetic field was generated by a DC solenoid cooled by water.The power consumption of the solenoid was28kW and the driving current was500A.The inner bore diameter was66mm.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,5min stable operation was realized.The output power was12kW with an electron beam of45kV,1.7A.The output efficiency was15.7%.
