Session: Near Detectors
Track: Near Detectors
A test experiment, T-59, to develop a 3D grid-like neutrino near detector with a water target for measurement of neutrino cross sections at the T2K near detector hall was approved by J-PARC PAC. We are developing the detector to reduce the uncertainty on neutrino cross sections for T2K oscillation analyses. A new idea, a 3D grid-like structure of scintillator bars, is adopted to detect tracks of c ... More

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 considerat ... More

A fine-grained, water-based liquid scintillator detector to replace the current passive water + plastic scintillator target in FGD2 in the T2K ND280 tracker system would allow the direct tracking of low energy hadrons emitted by neutrino interactions on oxygen. We are currently building a 1-cell prototype using the WbLS developed at BNL to test for light output.

In current Super-K calibration, we need much manpower and working time. We have to automate these works in Hyper-K, which is 20 times larger than Super-K. We are planning to install a new deployment system in the Super-K detector as one of R&D's for Hyper-K. We report the current status.

HK will require software to interface between atmospheric flux models, the HK detector geometry, and neutrino interaction simulators as the first step in an atmospheric MC. This talk will introduce software currently under development for SK which is intended to be easily portable to an experiment like HK, and easily expandable to non-atmospheric neutrino fluxes.

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 Z/A ... More
