Design and experimental progress of a 105/140 GHz dual-frequency MW-level gyrotron

  • 摘要: 介绍了105/140 GHz双频兆瓦级回旋管的设计和最新实验进展。该回旋管的谐振腔、准光模式变换器、BN输出窗采用了双频共用的设计,电子枪采用了双频复用的双阳极磁控注入枪,收集极采用单级降压。在现有实验室电网功率容量有限的情况下,进行脉冲调试,得到的实验结果为:在重频1 Hz、ms连续短脉冲条件下,在105 GHz点和140 GHz点脉冲功率分别达到710 kW和1.057 MW,脉宽0.7 ms,对应总效率分别为34%和49%。在105 GHz点通过脉宽延展和老炼,进一步得到300 kW/2 s和400 kW/1 s的秒级脉宽实验结果,BN窗片的温度在两种状态下温度分别达到606 ℃和503 ℃,波束频率单一,没有杂模。实验基本上验证了该器件的物理设计。
