The radiation-frequency locking by an external signal is experimentally studied for a megawatt gyrotron. An external signal from a magnetron is applied to the operation space of the gyrotron at a frequency of 35 GHz via a synthesized two-mirror quasioptical converter developed at the Institute of Applied Physics of the Russian Academy of Sciences. The radiation spectra are measured for both the frequency locking regime and the frequency beats. The locking region is constructed on the plane of two parameters, namely, the external-signal power and frequency. The experimental and theoretical results are compared to show a good agreement.

外信号对兆瓦回旋管振荡方式影响的实验研究

对兆瓦陀螺仪通过外部信号的辐射频率锁定进行了实验研究。来自磁控管的外部信号通过俄罗斯科学院应用物理研究所开发的合成双镜准光转换器以 35 GHz 的频率施加到回旋管的工作空间。测量频率锁定机制和频率拍频的辐射光谱。锁定区域构建在两个参数的平面上，即外部信号功率和频率。将实验和理论结果进行比较，显示出良好的一致性。
