Abstract

A novel mechanism of superradiance (SR) in the process of stimulated backscattering of powerful pump wave by intense electron bunch has been studied. Using a relativistic 38 GHz BWO as a pump wave source, the short SR pulses of scattered radiation were observed experimentally. Due to the Doppler up-shift, spectrum of scattered pulse included the frequencies up to 150 GHz. After modifications the same experimental set-up will be used for observation of effect of amplification of subnanosecond SR pulse propagating along nanoseconds electron beam. According to PIC-code simulations under experimental conditions output pulse peak power can exceed the power of driving electron beam.
