In a non-stationary numerical experiment, it is shown that introducing the reflections at the ends of the slow wave structure of a relativistic backward-wave oscillator operating in the superradiance mode provides the conditions for the formation of a sequence powerful ultrashort microwave pulses during a single pulse of the current. The conversion factor, defined as the ratio of the peak power of an ultrashort pulse to the power of an electron beam, is about 3 for the first (main) pulse and decreases to ≈ 2 for subsequent pulses
