Description
The Shanghai Laser Electron Gamma Source (SLEGS) is one of the beamlines at the SSRF, producing energy-tunable gamma-ray beams via laser Compton slant-scattering (LCSS) of 10.64 μm laser photons from a CO₂ laser off 3.5 GeV electrons. We confirmed the generation of gamma-ray beams in the energy range from 0.66 MeV to 21.7 MeV, with an energy scanning accuracy of 20 keV. At the SLEGS beamline, an NRF (Nuclear Resonance Fluorescence) detection system based on 4 HPGe detectors and 8 LaBr₃ gamma detectors has been established. In addition, a flat-efficiency neutron detection system (FED) based on ³He neutron counters and a neutron time-of-flight detector (n-TOF) based on EJ301 liquid scintillator detectors have also been established. Based on this Gamma/Neutron Detection System, SLEGS has carried out a number of high-quality experiments.
