【Abstract】 We propose a build to low energy γ ray beam line (SLEGS Ⅰ) at the Shanghai Synchrotron Radiation Facility (SSRF). By Compton back scattering (BCS) of infrared or far infrared laser lights from 3.5 GeV electrons circulating in the storage ring of SSRF, high intense quasi monochromatic BCS γ rays with high linear or circular polarization ranging 1-25MeV will be produced. It can be widely applied to fundamental researching fields of nuclear physics, nuclear astrophysics and related applications. In this paper, we briefly present the outline of BCS theory and the properties of BCS γ ray with numerical compution based on the major parameters of SSRF storage ring.更多还原
