Study on single-channel signals of water Cherenkov detector array for the LHAASO project

Callibration of a homemade 4-fold Water Cherenkov Detector array, by detection of EAS events

Gadolinium 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...

First Study of Neutron Tagging with a Water Cherenkov Detector

A first study of neutron tagging is conducted in Super–Kamiokande, a 50,000-ton water Cherenkov detector. The tagging efficiencies of thermal neutrons are evaluated in a 0.2 % GdCl3-water solution and pure water. They are determined to be, respectively, 66.7 % for events above 3 MeV and 20 % with corresponding background probabilities of 2 × 10 and 3 × 10. This newly developed technique may ena...
