摘要：
We study, both theoretically and experimentally, a relativistic backward wave oscillator BWO with a discrete resonance reflector. It is shown that premodulation of electrons in the reflector region leads to considerable changes in the oscillator characteristics. If a homogeneous slowingdown system (SS) is considered and the space charge is neglected, then the calculated maximum efficiency of oscillation increases from 15% without modulation to 58% in the case of optimal modulation. A pulse-periodic mode of microwave oscillation with pulsed power 0.5 GW at wave-lengths λ ≈3 cm was reached in the experiment. © 1999 Kluwer Academic/Plenum Publishers.
