Abstract :
A narrow-band high-efficiency FEL-oscillator with a Bragg resonator was constructed based on a linear induction accelerator which formed a 1MeV, 200A, 200ns electron beam. At the frequency 31GHz radiation with power 31MW and efficiency 25% was measured. High efficiency and narrow spectrum width of spectrum was achieved by the selective properties of the Bragg resonator in combination with the high quality of the helical electron beam formed in the reversed guide field regime.
