Effects of Radiation Damping on Beam Quality in the Inverse Free Electron Laser Accelerator.

Abstract

The effect synchrotron radiation damping on the transverse beam emittance for an inverse electron laser (IFEL) accelerator is studied. A beam envelope equation is derived and solved for an arbitrarily tapered wiggler field. The expression for the evolution of the normalized transverse beam emittance is derived and found to decrease exponentially with distance due to radiation damping, until it is limited by quantum excitation. The beam envelope equation is integrated both analytically and numerically for a set of IFEL accelerator parameters. Our results show that for acceleration distances comparable to the radiation damping e-folding length, substantial improvements in the beam quality can be realized. Keywords: Beam quality; Radiation damping, Free electron lasers.
