F. Ciocci et al., COMPTON BACKSCATTERING INDUCED BY FEL PHOTONS - A GENERAL TREATMENT, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 393(1-3), 1997, pp. 536-539
We discuss a general method of analysis for the Compton backscattering
of FEL intracavity photons. We present general formulae for the photo
n yield both for linac-based and recirculated FELs. We also discuss Co
mpton backscattering of X-ray FEL photons produced by high gain device
and analyze the possibility of realizing a gamma-ray facility with ph
oton energy ranging from 70 to 800 MeV.
