Novel Quasi-Optical Tunable Radiation Source
-
Abstract
This paper describes a novel quasi-optical tunable radiation source with relativistic electron beam of middle energy and a quasi-optical resonator complied with diffraction grating and three-mirror reflector. Coherent radiation with peak power of several tens of kW at 3mm waveband is successfully detected from an experimental facility characterized by beam energy of 400—500 kV, pulse length of 70 ns, pulse beam current of 0.2 kA, and pulse magnetic field of up to 1.2 T.
