Paper Abstract

A complete, 3D theory of Compton scattering is described, which fully takes into account the effects of the electron beam emittance and energy spread upon the scattered x-ray spectral brightness. In the linear regime, and in the absence of radiative corrections; it is found that each vacuum eigenmode gives rise to a single Doppler-shifted classical dipole excitation. This formalism is then applied to Compton scattering in a 3D laser focus, and yields a complete description of the influence of the electron beam phase space topology on the x-ray spectral brightness; analytical expressions including the effects of emittance and energy spread are also obtained in the 1D limit. Within this framework, the x-ray brightness generated by a 25 MeV electron beam is modeled, fully taking into account the beam emittance and energy spread, as well as the 3D nature of the laser focus; its application to x-ray protein crystallography is outlined.
