Abstract
The first results of the observation of superradiance from a single, subnan osecond, high current, electron bunch passing through a wiggler immersed in a guide magnetic field are presented. The 300-500 ps microwave pulses were generated in the high gain regime for both the conventional and reverse di rections of the guide magnetic field. The dependence of the radiation power on the interaction length as well as the absolute value of the power, 100- 200 kW, were related with the development of self-bunching and consequently with coherent emission.
