Abstract
Intense microwave pulses (several hundreds of kilowatts) of ultrashort duration (less than 0.5 ns) were obtained from an ensemble of electro ns rotating in a uniform magnetic field. The comparison with theoretic al simulations proves that this emission can be interpreted as cyclotr on superradiance. The maximum radiation power was achieved under group synchronism conditions, when the electron bunch translational velocit y coincides with the group velocity of the wave propagating in the wav eguide.
