摘要

本文介绍了基于稳态理论的射频场轴向不固定(自洽)回旋管的起振荡条件计算方法。给出了远端负载延迟反射的0.4太赫兹二次谐波回旋管在不同反射信号参数下的启动振荡电流和启动振荡频率的计算。在固定波束电流下，反射幅度的增加导致观测到的振荡区数量增加，从而扩大了频率可调谐范围。

Self-Consistent Calculation of Start-Oscillation Conditions in a Gyrotron with Reflections

The method for calculation of start-oscillation conditions based on the stationary theory of a gyrotron with non-fixed (self-consistent) axial profile of the RF field is described. The calculations of start-oscillation currents and start-oscillation frequencies are presented for the 0.4-THz second-harmonic gyrotron with delayed reflections from the remote load at different parameters of the reflected signal. Increase of the reflection magnitude leads to increase of the number of oscillation zones observed at fixed beam current and, thus, to is extension of the frequency tunability range.
