Abstract :
It is demonstrated that pulse shortening occurring in the relativistic BWO at gigawatt power level is accompanied by formation of explosive-emission plasma on the surface of 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.
