摘要

结果表明，在千兆瓦级相对论BWO中，脉冲缩短伴随着波形慢波结构表面出现爆炸发射等离子体。微波发射的终止是用等离子体发射的电子对工作电磁波的吸收来解释的，而等离子体发射的正离子的存在从根本上增加了吸收的强度。

Mechanism of microwave pulse shortening in the relativistic backward wave oscillator

It is demonstrated that pulse shortening occurring in the relativistic BWO at gigawatt power level is accompanied by the appearance of an explosive-emission plasma on the surface of the corrugated slow wave structure. Termination of microwave emission is explained in terms of absorption of the operating electromagnetic wave by electrons emitted from the plasma while the intensity of absorption is radically increased by the presence of positive ions emitted from the plasma.
