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