1 Multi - Megaton Water Cherenkov Detector for a Proton Decay
The discovery of the neutrino oscillations in 1998 revisited the interest of proton decay search [2]. The existence of the tiny neutrino mass indicates the existence of the large energy scale behind and suggests the connection between the small neutrino mass and proton decay. There are strong indications of the unification scale of O(10 16)GeV: the running coupling constants with super-symmetri...
متن کاملStudy of 1 Megaton water Cherenkov detectors for the future proton decay search
The sensitivity of a possible future 1 Megaton water Cherenkov detector for proton decay searches was studied. For p e π0 decay mode, the detection efficiency and the number of atmospheric neutrino backgrounds were estimated by using a detailed Monte Carlo simulation program. Moreover, their dependence on the number density of the photomultiplier tube (PMT) was investigated. With the PMT densit...
متن کاملGadolinium study for a water Cherenkov detector
Modification of large water Cherenkov detectors by addition of gadolinium has been proposed. The large cross section for neutron capture on Gd will greatly improve the sensitivity to antielectron neutrinos from supernovae and reactors. A five-year project to build and develop a prototype detector based on Super-Kamiokande (SK) has started. We are performing various studies, including a material...
متن کاملFeasibility of a Next Generation Underground Water Cherenkov Detector: UNO
The feasibility of a next generation underground water Cherenkov detector is examined and a conceptual design (UNO) is presented. The design has a linear detector configuration with a total volume of 650 kton which is 13 times the total volume of the Super-Kamiokande detector. It corresponds to a 20 times increase in fiducial volume for physics analyses. The physics goals of UNO are to increase...
