Hyper-Kamiokande (HK) is a next-generation international neutrino experiment currently under construction in Japan. HK will explore proton decay and have the capability to detect Earth-crossing, atmospheric, solar, cosmic, and accelerator neutrinos. Expected to start data collection in 2027, HK will require periodic calibration for optimal performance.
The calibration at lower energies will involve utilizing a Deuterium Tritium neutron Generator (DTG), entailing the generation of a radioactive N16 cloud strategically positioned in various locations within the water tank.
A simulation of N16 cloud generation and decay was conducted in preparation for propagating the decay products through the detector volume using dedicated HK simulation software. The DTG will be deployed using a computer-controlled crane to achieve accurate positioning while prioritizing the cleanliness and safety of the detector.
