Abstract

The spontaneous pulse shortening occurring in the relativistic backward wave oscillator (BWO) in a gigawatt power level was experimentally and theoretically investigated. Results showed that the phenomenon was accompanied by formation of explosive-emission plasma at the surface of a corrugated slow wave structure and by appearance of intense electron flows between the SWS ripples. The termination of microwave emission was explained in terms of the increase of the BWO starting current due to partial absorption of the operating electromagnetic wave by electrons emitted from the plasma, while the intensity of the absorption radically increased owing to the presence of positive ions emitted from the plasma.
