本文对具有最小衍射Q值的开放腔回旋管提出了一种非定常理论。回旋管是由一组自洽的方程，考虑到电子束上的电子聚束是由相同的轴向结构定义的微波振荡的轴向结构的依赖。作为非平稳过程的结果，恒定振幅的振荡建立了一个中等值的束流。随着束流的增长，自动调制和随机振荡发生，它们的光谱特性。结果表明，在该区域的参数接近最佳效率的恒定振幅振荡建立在低Q谐振器的回旋管。
A non-stationary theory is developed for gyrotrons with open resonators that have a minimum diffraction Q. The gyrotron is described by a self-consistent set of equations taking into account the dependence of the axial structure of microwave oscillations on the electron beam where electron bunching is defined by the same axial structure. As a result of non-stationary processes constant-amplitude oscillations are established for a moderate value of the beam current. As the beam current grows, automodulation and stochastic oscillations take place; their spectral characteristics are presented. It is shown that in the region of parameters close to optimum for efficiency constant-amplitude oscillations are established in gyrotrons with low-Q resonators.
