Experimental study of a FEM based on a 2D distributed feedback cavity

Abstract:
We report operation of a co-axial Free-Electron Maser (FEM) based on two-dimensional distributed feedback. The 37.3GHz FEM was driven by an annular electron beam (475kV, 500A, 250ns) and generated 15MW ±1.5MW of radiation with a 6% conversion efficiency. To investigate an increase in FEM output power and efficiency a new cavity configuration based on a copper 2D Bragg reflector will be studied. ©2005 IEEE.
