Abstract

Hyper-Kamiokande is a next-generation water Cherencov detector for neutrino physics. Its large volume (260 kton × 2) allows Supernova burst (SN) neutrino and Supernova Relic Neutrino (SRN) search much more promising than current Super-Kamiokande detector (50 kton). With an alternative plan of locating one of the two identical detectors to Korea, better physics sensitivities are expected because of less muon flux and its spallation isotopes due to more overburden in Korean candidate sites than Japanese Hyper-Kamiokande site (Tochibora). According to our study using simple MC 102 SRN events (5.2 sigma) in a Korean site and 71 SRN events (4.2 sigma) in the Japanese site are expected for 10 years of operation for one detector. Sensitivity studies using a full MC will be performed in the near future.
