Outline of Final Research Achievements |
The study of pulse shape discrimination for the inorganic scintillators including Gd was performed. GSO and GAGG crystals ware used for the scintillator and alpha ray and gamma ray ware used for the incident particles. As the result, It was found that GSO crystal can not separate the events of these two particles using PSD method at the room temperature , but GAGG crystal can separate the events using shape indicator method clearly. From this result, we tried the internal alpha/gamma event separation using large GAGG crystal for the basic study of the double beta decay experiment using GAGG. The quenching factor for alpha/gamma was also investigated using He ion beam.
