Outline of Final Research Achievements

In this research, we developed a high energy resolution detector which is very important for neutrino-less double beta decay search. The scintillating bolometer with undoped calcium fluoride scintillation crystal containing 48Ca isotope, which has the highest Q value among double beta decay isotopes, was used. The crystal was cooled down to an extremely low temperature of 10 mK. We developed a method to simultaneously detect scintillation light in addition to heat quantity. Compare the signal intensities of both light and heat, types of particles can be identified.
It was succeeded for the first time to realize the scintillating bolometer detector using the undoped calcium fluoride crystals during the research period. This achievement is an important step toward future high-sensitivity, large-scale neutrino-less double beta decay study using 48Ca isotope.
