摘要: Energy-variable gamma-rays are produced in laser Compton slant-scattering (LCSS) mode at the Shanghai
Laser Electron Gamma Source (SLEGS), a beamline of the Shanghai Synchrotron Radiation Facility (SSRF, also
called Shanghai Light Source). Based on the SLEGS energy-variable gamma-ray beam, a positron-generation
system composed of a gamma-ray-driven section, positron-generated target, magnet separation section, and
positron experimental section was designed for SLEGS. Geant4 simulation results show that the energy tunable
positron beam in the energy range of 1 to 12.9 MeV with a flux of 3.7×104 to 6.9×105 e +/s can be produced in
this positron-generation system. The positron beam generation and separation provide favorable experimental
conditions for conducting non-destructive positron testing on SLEGS in the future. The positron-generation
system is currently under construction and will be completed in 2025.
