Nonlinear dynamics of a gyrotron with high-order operating mode, driven by an external signal with harmonic or stepwise modulation of its parameters or by two monochromatic signals, was studied theoretically. Conditions for locking and control of the radiation frequency were found. Exit from the locking regime is accompanied by the beats of the operating mode or excitation of spurious modes. Simulations were performed using a megawatt-power TE_28.12 mode gyrotron as the example (Chirkov et al., Appl Phys Lett 106(26), 2015).

具有谐波或逐步调制参数的外部信号对高功率回旋加速器操作的影响

理论上研究了高阶工作模式回旋管的非线性动力学，该动力学是由具有谐波或对其参数进行逐步调制的外部信号或两个单色信号驱动的。找到了锁定和控制辐射频率的条件。退出锁定状态时会伴随着操作模式的跳动或伪模式的激发。以兆瓦功率TE _28.12模式回旋管为例进行了仿真（Chirkov等人，Appl Phys Lett 106（26），2015）。
