摘要：

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 electron pulse length is 30 ns full width at half maximum with a peak current of 400 A. The FEL is designed to operate in the high-gain Compton regime, with a negative coupling parameter (phi<0) leading to a strong 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 results are in good agreement with predictions made using the three-dimensional stationary simulation code SOLITUDE.
