| Outline of Final Research Achievements |
A GAGG crystal which has high light yield and fast response of light emission (decay constant) is expected to be better scintillation counter for the high energy use. We developed large size crystal, 5-cm diameter and 10-cm long, and evaluated its performance. Using remarkable property of changing decay constant by doping Mg in GAGG crystal, we also made 20-cm long crystal which is joint of the No-Mg-doped and Mg-doped 10 cm long crystals. Such crystal which has 2 decay constant would has a capability of separation for photon and neutron by comparing signal shapes. This GAGG crystal was evaluates by 200 - 800 MeV positron beam and obtained data is well reproduced by the Monte-Carlo simulation.
