Due to the cooling requirements, the use of a thick Bremsstrahlung target for electron to photon conversion is a difficult technical challenge in this intensity regime. Here we present a different concept in which electrons are injected into a small storage ring to make multiple passes through a thin internal photo-conversion target, eventually depositing their remaining energy in a cooled central core absorber. We discuss the design requirements and propose a set of design parameters for the Fixed Field Alternating Gradient (FFAG) ring. Using particle simulation models, we estimate various beam properties, as well as the MPS for the electron loss.
