Abstract
Coherent microwave and millimeter wave emission from a rotating electron beam in a circular wiggler magnetic field (circular free electron laser) has been studied. The circular wiggler, which consists of a coaxial waveguide and an azimuthally periodic magnetic field, is compact as compared with a conventional linear FEL. Tunable radiation frequency (TM coaxial waveguide mode) was observed to be typically 11–38 GHz using a mildly relativistic electron beam of energy less than 500 kV, about 150 A current and about 8 μs pulse width. The total radiation power was about 840 kW at 11.5 GHz of TM 6,1.
