Ns. Ginzburg et al., EXPERIMENTAL-OBSERVATION OF SUPERRADIANCE IN MILLIMETER-WAVE BAND, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 393(1-3), 1997, pp. 352-355
The first experimental results of the observation of superradiance fro
m a single subnanosecond electron bunch are presented. Superradiance w
as associated with different varieties of stimulated emission (bremstr
uhlung, cyclotron, Cherenkov, etc). Unique megawatt power level microw
ave pulses of short duration (0.3-0.5 ns) have been obtained.
