Description
In July 2020, Super-Kamiokande (SK) loaded 0.011% of gadolinium to enhance the detection efficiency of neutron signals and restarted the observation as “SK-Gd experiment”. One of the purpose of SK-Gd experiment is understanding the supernova mechanism as well as the star formation history by detecting Supernova Relic Neutrinos (SRNs). To detect SRNs in SK-Gd experiment, it is necessary to estimate atmospheric neutrino backgrounds using a simulation with a more accurate neutron transport model. For the reason, Geant4-based detector simulation program was developed and now we are proceeding the performance evaluation of it. In this poster, we report the results of the comparisons of basic distributions for the particles, whose energy is the order of GeV, from the Geant4-based simulation program with the current SK official GEANT3-based simulation results.
