Abstract
It has been suggested that for a given output wavelength, electron energy requirements could be greatly reduced in a two stage FEL. The principal of a two-stage device has been demonstrated in an experiment where the same intense relativistic election beam first produces 500 MW of 12.5 GHz radiation through a backward-wave-oscillatior (BWO) process, and then uses the BWO radiation as a wiggler for an FEL operating at ~200 GHz. Improvements in the initial experimental configuration which will optimize the 200 GHz emission are described.
