Outline of Final Research Achievements

Majorana neutrinos could play the central role in explaining the origin of our matter-dominated universe and light neutrino mass. Neutrinoless-double-beta decay is only unique scheme to study Majorana neutrino. We proposed the new experiment based on superconducting detector for high sensitive search. We have demonstrated the use of superconducting detector, here we use Microwave Kinetic Inductance Detector (MKID), as high performance radiation detector. We have also validated to fabricate MKID on NdGaO3 and CaF2, which includes the double beta decay nucleus.
