Outline of Final Research Achievements

Core collapse supernova explosions are among the most dramatic and important events to take place in the universe. This research is a study of the correlation between neutrino and gravitational wave by supernova explosion, and aimed at developing the world's most advanced-technology supernova neutrino detector. In April 2015, the EGADS detector has been full of water enriched with 0.2% gadolinium sulfate, equipped with new electronic circuits and computers, and began operation as a water Cherenkov detector capable of neutron capture with high efficiency. In addition, we studied the prediction of signal correlation of neutrino and gravitational wave when neighboring supernovae occurred.
