Abstract

A set of self-consistently nonlinear and coupled equations in three dimensions, describing the evolutions of both radiation field and electrons is obtained. In the model utilized in the analysis, a relativistic electron beam with an arbitrary radial profile is injected into the interactional region of an amplifier. Focus is placed on the effects of the wiggler field amplitude and a dc magnetic-field amplitude, electron beam, and input-signal power. Experimental results show increases in efficiency up to 9 percent, and it is noted that higher efficiency rates are possible.
