Stable pulse-periodic source of GW-level nanosecond microwave pulses

Recent studies of the generation of GW-level nanosecond microwave pulses in extended BWO-type slow-wave structures have been showed an opportunity for stabilization of the RF field phase. Decline in the dependence of the output microwave power on the electron energy in this operation mode allows reaching radiation peak power spread not exceeding voltage variation on a vacuum diode. Superradiative microwave generators can produce high peak power with moderate beam energy and have good efficiency. This paper discusses the possible application of such systems.
