Simulation study on the optical processes at deep-sea neutrino telescope sites

The performance of a large-scale water Cherenkov neutrino telescope relies heavily on the transparency surrounding water, quantified by its level light absorption and scattering. A pathfinder experiment was carried out to measure optical properties deep seawater in South China Sea with light-emitting diodes (LEDs) as sources, photon multiplier tubes (PMTs) cameras sensors. Here, we present an simulation program employing Geant4 toolkit understand scattering processes seawater, which helps extract underlying from experimental data. results are compared data show good agreements. We also verify analysis methods that utilize various observables PMTs this program, can be easily adapted other experiments future detectors.
