| Outline of Final Research Achievements |
A liquid scintillator (LS) detector has a sensitivity of low-energy anti-neutrino. On the other hand, the detector can not measure directional information of anti-neutrino in principle. Development of Li-leaded LS was already complete. Our idea is using fibers to reconstruct a direction of anti-neutrino in Li-loaded LS by measuring light emotion points precisely. We found material which had chemical compatibility and developed a method for processing of fibers. Furthermore, we designed a structure of fibres in Li-loaded LS container and developed prototype detector. We are ready to measure light emotion by radioactive sources using the detector.
