| Research Abstract |
For large-volume, ultrapure liquid scintillator detector, like KamLAND, basic R&D has been performed for a new method to measure arrival direction of electron antineutrinos, and particle ID. By taking photographs of light emission vertex, the position resolution was measured at 5 cm for 1-MeV gamma ray, being improved from the current resolution of 15 cm. For “Li-6 liquid scintillator", that we have developed before, the neutron capture time and the energy of the alpha ray emitted after capturing neutrons were measured. With those data, we performed a simulation for directional measurement of geoneutrinos.
