Abstract :
A compact repetitive superradiative Ka-band BWO is described, and the results of a study of its characteristics are presented. For an electron beam transported in a magnetic field of 2 T, which is less than the value corresponding to a cyclotron resonance, the efficiency of the conversion of electron beam power to pulsed electromagnetic radiation is close to unity. The peak power of an electromagnetic superradiative pulse of 250-ps duration is ~ 500 MW.
