| Outline of Final Research Achievements |
This research aims to develop new scintillator using calcium iodide (CaI2) and to evaluate the performance of CaI2 scintillator. We have grown CaI2 scintillator crystal by BS method and high light yield of 107,000 photon/MeV was achieved. Additionally, we tried Ca(Br,I)2 crystal growth in order to overcome strong cleavage of CaI2. As a result, light yield of Ca(Br,I)2 was 95,400 photons/MeV and it is high enough for dark matter search experiment.
