摘要：
We have studied a periodic pulse train regime (1 s, 50 Hz) of a relativistic backward wave oscillator with a resonant reflector, which can be mechanically tuned from pulse to pulse within a frequency band of 9% on a level of -3 dB of the maximum in the entire microwave peak power range in a magnetic field of 0.36 T. The maximum peak power in a pulse train amounted to 2.5 GW at a frequency of 3.6 GHz, an efficiency of 20%, and a microwave pulse duration of 20 ns.
