Outline of Final Research Achievements

We have developed for the methods based on the high xenon gas concentration liquid scintillator under the pressurized environment to realize the next generation neutrino-less double beta decay search experiment to verify Majorana neutrino property. Especially we have searched suitable components of liquid scintillator, improved how to use super clean room to avoid container surface contamination which has become problems in underground experiments, developed and technically demonstrated about scintillating container which can reduce container origin backgrounds.
