A new method to generate ultrahigh-power microwave pulses compatible with mildly relativistic electron sources is proposed. This method involves a novel microwave compressor in the form of a metal helically corrugated waveguide, which can enhance the power of frequency-modulated nanosecond pulses up to the multi-gigawatt level. The results of the proof-of-principle experiments at kilowatt power levels are in good agreement with theory.
