Abstract :
In experiment, mechanical pulse-to-pulse frequency tuning was realized in a repetitively pulsed (1 s, 50 Hz) relativistic backward-wave oscillator with a resonant reflector in a 0.36-T magnetic field. The tuning bandwidth was ≈ 9 % at a level of −3 dB of microwave peak power. The microwave peak power in a batch was 2.5 ± 0.6 GW at a frequency of ≈ 3.6 GHz, an efficiency of 20 ± 4 %, and a microwave pulsewidth of ≈ 20 ns.
