Abstract
A narrow-band Free-Electron Maser (FEM) oscillator with a Bragg resona tor was operated in the reversed guide field regime. A high-current ac celerator generated the 300 keV, 30 A, 100 ns electron beam. Radiation at 32 GHz frequency and 500 kW power, corresponding to similar to 5% efficiency, was measured. The measured FEM parameters agreed with pred ictions of a numerical simulation. The observed radiation frequencies compared well with ''cold'' microwave calibration of the cavity.
