Lattice and beam dynamics for the pulse mode of the laser-electron storage ring for a Compton x-ray source

Abstract

We present the lattice design for the pulse mode of the compact laser-electron storage ring for a Compton x-ray source. The lattice is optimized to suppress the intrabeam scattering (IBS), which is the dominant factor that leads to emittance growth. To better simulate the beam dynamics in the pulse mode, we developed a macroparticle 3D Monte Carlo algorithm. The IBS module can perform an element-to-element calculation to evaluate the emittance change due to IBS, while the Compton scattering module can provide the spatial and temporal information of the x-ray photon yield. Parameters of the storage ring, electron beam, and scattered photon yield of the pulse mode of this Compton x-ray source are presented.
