Outline of Final Research Achievements

Re-analysis of past reactor neutrino experiments is suggesting the existence of the 4th neutrinos. KamLAND experiment that has achieved important measurements of the neutrino oscillation parameters has a potential to explore the 4th neutrinos.
Technical design of implementing an anti-neutrino generator into the KamLAND has been developed in this study. It has been shown that it is feasible to perform an experiment to explore the 4th neutrinos with KamLAND.
