Physics Potential
Neutrino oscillation is sensitive to the electron density of the media. Hyper-K has a potential to measure the electron density of the deep Earth by measuring atmospheric neutrino oscillation. By combining the electron density and the matter density, we can measure the average chemical composition as the ratio of atomic number (Z) to atomic mass (A). We report the sensitivity of Hyper-K as the...

Near Detectors
The Tokai Intermediate Tank with Unoscillated Spectrum (TITUS) is a proposed new near detector for the Hyper-Kamiokande beam programme. The baseline design for TITUS features a 2 ktonne water Cherenkov (WC) detector at a distance of ~2 km from the J-PARC neutrino beam. TITUS is a 'next-generation' WC detector, including technological advances such as gadolinium-loading, and LAPPD photosensors....

We clarify the design of the magnetized Muon Range Detector (MRD) for the proposed TITUS intermediate detector. Such an magnetized MRD would contain muons from interactions in the water Cherenkov detector, and would lend an extra advantage to the detector - the capacity to distinguish meutrino and antineutrino events, through the observation of the muon charge. We address both practical...
