在相对论性亚吉瓦级Ka波段返波振荡器中，当慢波结构几何形状、加速电压和电子束流保持不变时，瞬态时间、微波脉冲宽度和峰值功率发生变化。这是考虑到BWO操作模式取决于启动电流与束流的比率。有效的变化的启动电流是通过改变束路径中的引导脉冲磁场扩散到电子注入区域和束波相互作用空间的时间之间的显着差异。
Variations in the transient time and in the microwave pulse duration and peak power have been demonstrated for a relativistic subgigawatt Ka -band backward-wave oscillator (BWO) with the slow-wave structure geometry, the accelerating voltage, and the electron beam current remained unchanged. This was done taking into account that the BWO operation mode depends on the starting-current-to-beam-current ratio. Efficient variation of the starting current was attained by changing the beam path in view of a significant difference between the times of the guide pulsed magnetic field diffusion into the electron injection region and beam-wave interaction space.
