“…Power output and efficiency are found to be governed by electron trapping in the potential well formed by the combined action of the ponderomotive and self-consistent space-charge forces. In contrast, the KMR model was previously examined for a Compton regime FEL with a different wiggler and waveguide configuration than ours, 6 where the space-charge effects were small.…”

We report measurements of the nonlinear radiation intensity and phase (wave refractive index) of a free-electron laser amplifier operating in the collective (Raman) regime. The laser generates up to -100 kW of rf power at a frequency of 9.3 GHz and with an efficiency of -10%. Power saturation, efficiency, synchrotron oscillations, and the rf phase are studied as functions of electron beam energy, current, and axial distance within the helical wiggler. Excellent agreement with nonlinear theory that takes cognizance of electron trapping in the combined ponderomotive and spacecharge potential well is obtained.

“…Instead, as in earlier work, 4 ' 6 a space charge reduction factor, pi, is utilized. This factor, which is ~ 0.5 for the parameters of our experiment, can be found in the literature 1 " (with corrections for -y > 1) for the case of an unbunched electron beam with a uniform density profile.…”
