Lattice design and beam dynamics in a compact X-ray source based on Compton scattering

We present a feasibility study of a particular X-ray source based on Compton scattering. In particular, we focus on the pulse mode of its operation, in which electron beams are injected with the frequency of 50–60 Hz. We propose to construct a compact storage ring with a circumference of 12 m, as well as a lattice to provide stable operation in the pulse mode for electron–laser interaction. We develop a computer code to simulate beam dynamics in the pulse mode. Intra-beam scattering and Compton scattering are included in the simulation, and their effects on beam emittance and stability are discussed. This source provides X-ray beam in the pulse mode with an intensity of ∼1.7×1012 photons/s and spectral brightness of ∼1010 photons/s/0.1%BW/mm2/mrad2 in the energy range from 20 to 80 keV. These parameters meet the requirements for angiography as well as other technological and scientific applications that require high brightness and pulse nature of X-ray.
