Abstract

The results of theoretical and experimental studies allowing the use of Cherenkov superradiance for the generation of electromagnetic pulses with a peak power higher than electron flow power are reported. For an injection current of 2.6 kA and a particle energy of 330 keV, the power of a microwave pulse with a carrier frequency of 9.3 GHz and a duration of 0.5 ns attained 1.2 GW.
