The Hyper-Kamiokande experiment is planned to start in 2027 aiming for precise measurement of neutrino oscillation using J-PARC neutrino beam including the search for CP violation. Hyper-Kamiokande detector is a 260 kiloton water Cherenkov detector and has large statical power, requiring systematic uncertainty at the 1% level or less on neutrino oscillation measurements. For this purpose, a new 1 kiloton scale Intermediate Water Cherenkov Detector (IWCD), which is based on the same detection principle as Hyper-Kamiokande is proposed to measure the neutrino flux and interaction cross section near the generation point of the neutrino beam before oscillation. The goal of IWCD is to reduce the systematic uncertainty in the long baseline neutrino oscillation measurement of the Hyper-Kamiokande experiment. Water Cherenkov Test Experiment (WCTE) is a 50 ton scale water Cherenkov detector and currently under preparation to evaluate the performance of IWCD. WCTE will use new photosensor technologies such as multi-PMT modules and will study the response of small water Cherenkov detectors to electron, muon, and hadron beams at CERN.
In this poster, we will present the performance of event reconstruction with the IWCD and WCTE detectors using the simulation.
