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.
Highlights
Compton scattering (CS) off a relativistic electron beam with an intense laser pulse is a promising way of producing x ray with high intensity
The basic principle of this scheme is the Compton scattering off a low-energy electron beam stored in a storage ring with an intense laser pulse stored in an optical storage system to produce the desired photon spectrum
With a 50 MeV, 10 ps electron beam scattering off laser photons with the energy Elas 1⁄4 1:467 eV, one can produce an x-ray pulse with a photon energy of Ex;max 1⁄4 56:4 keV and a pulse length of 10 ps
Summary
Compton scattering (CS) off a relativistic electron beam with an intense laser pulse is a promising way of producing x ray with high intensity. The basic principle of this scheme is the Compton scattering off a low-energy electron beam stored in a storage ring with an intense laser pulse stored in an optical storage system to produce the desired photon spectrum. The other scheme is the pulse mode of operation [3] In this mode, the electron beam is injected and stored for a short period of time (we call it the storage period) during. We proposed a lattice design for the pulse mode of the laser-electron storage ring to store the electron beam and provide stable interaction between the electron and the laser photon. Since the storage time of the electron beam in the ring is relatively short, we adopted a macroparticle algorithm originated from the binary collision model [4] to simulate the IBS effect.
