我们提出了一种非常显著地提高工作在短RF脉冲超辐射的非定常区域的反向波电子振荡器的峰值功率的方法。这种方法是基于分段的：规则的自激振荡器分段由提供超辐射脉冲放大的分段支撑。为了避免寄生自激和提高电子-波相互作用的效率，在放大部分采用了谐振参数的轮廓。在这样的系统中，转换系数(射频脉冲功率与电子束功率之比)可以达到几百%。
We propose a method for a very significant increase of the peak power of a backward-wave electron oscillator operating in the non-stationary regime of the super-radiation of short rf pulses. This method is based on sectioning: a regular self-oscillator section is supported with a section providing amplification of the super-radiant pulse. Profiling of a resonant parameter in the amplifying section is used to avoid the parasitic self-excitation and to increase the efficiency of the electron-wave interaction. In such systems, the conversion factor (the ratio between the rf pulse power and the electron beam power) can achieve a few hundred percent.
