Abstract
The narrow-band high-efficiency FEL-oscillator with Bragg resonator op erated in the reversed guide field regime was realized on the basis of linear induction accelerator formed 1 MeV, 200 A, 200 ns electron bea m. At a frequency of 31 GHz radiation with a power of 23 MW and an eff iciency of 19% was registrated. The measured frequency bandwidth was l ess than the tune of effective reflection of the Bragg mirrors. The na rrow width of the spectrum was encouraged by the selective properties of the Bragg resonator in combination with the high quality of the hel ical electron beam formed in the reversed guide field regime.
