Outline of Final Research Achievements

The development of a liquid scintillator detector to search for the Majorana neutrino mass was performed. We found that molecular sieve and activated charcoal are effective to remove light absorbing materials in the liquid scintillator, resulting in improved performance. The increase of the light output and transparency of the scintillator will enhance the detector performance. The present study enables us to reduce the cost of constructing a large detector and increases the chance of observing the Majorana neutrino mass with a liquid scintillator detector.
