Abstract :
The presence of plasma affects drastically the operation of microwave devices driven by high-current relativistic electron beams. Loading vacuum microwave oscillators with plasma changes the power and frequency band of the radiation. The Cherenkov plasma maser, that operates only with plasma inside, has both promising advantages and inherent disadvantages comparatively to the vacuum devices. Besides, plasma appears in a relativistic microwave oscillator spontaneously under the influence of high-power microwaves or electron fluxes; this parasitic plasma causes microwave pulse shortening, mainly in devices operating in the microsecond regime. The large body of experimental research carried out in relativistic plasma microwave electronics since 1970 up to now is the subject of this review
