Abstract

A high energy photon source (10) for generating photons of a first wavelength. The photon source (10) is constructed from an accelerator (13) that generates an electron beam. The electron beam is used to generate photons of a second wavelength which are then reflected back onto the electron beam to produce photons of the desired first wavelength via the back scattering of the generated photons. Here, the first wavelength is significantly shorter than the second wavelength. In the preferred embodiment of the present invention, the electrons are stored in a storage ring which includes an RF cavity (32) for replenishing the energy lost by electrons that underwent back scattering events that generated photons of the first wavelength. The storage ring assures that electrons are re-used thereby increasing the efficiency of the photon source (10).
