Simulation and Test of the SLEGS TOF Spectrometer at SSRF

Taking the neutron time-of-flight spectrometer of Shanghai Laser Electron Gamma Source as the object, the open source Monte Carlo program Geent4 is used to realize the simulation research on the performance and methodology of the spectrometer. The offline test data is obtained by using the experimental measurement results of the radioactive source and detectors, and processing and analysis with the root program of CERN.
