Abstract
A high-power relativistic microwave oscillator with low magnetic field is created based on a backward wave oscillator (BWO) with resonance reflector. For fixed parameters of the slow-wave structure (SWS) and the electron beam, the oscillation frequency of this BWO can be mechanically tuned within a 12% band by moving the resonance reflector relative to the SWS. A maximum output pulse radiation power of 4±1 GW at a working frequency of 3.6 GHz is achieved with a magnetic field of 4.6 kOe.
