An Intense $\gamma$-ray Beam Line of 10 MeV Order Based on Compton Backscattering

Abstract

Shanghai Laser Electron Gamma Source, a $\gamma$-ray beam line of 10MeV order was proposed recently. The beam line is expected to generate $\gamma$-ray with maximum energy of 22MeV by backward Compton scattering between CO${}_2$ laser and electron in the 3.5GeV storage ring of future Shanghai Synchrotron Radiation Facility. The flux of non-collimated $\gamma$-ray can be 10${}^9$ $\sim$ 10${}^{10}$s${}^{-1}$ if a commercial CO${}_2$ laser of 100W order output power is employed and injected with optimized settings.
