Abstract
We present the results of a free-electron-laser (FEL) experiment at 35 GHz, using a strongly relativistic electron beam (T=1.75 MeV). The el ectron pulse length is 30 ns full width at half maximum with a peak cu rrent of 400 A. The FEL is designed to operate in the high-gain Compto n regime, with a negative coupling parameter (phi<0) leading to a stro ng growth rate. More than 50 MW of rf power in the TE(11) mode (43 dB gain) has been obtained with good reproducibility. The experimental re sults are in good agreement with predictions made using the three-dime nsional stationary simulation code SOLITUDE.
