Growth and scintillation properties of 3Â in. diameter Ce doped Gd3Ga3Al2O12 scintillation single crystal

The 3 in. size Ce1%:Gd3Al2Ga3O12 single crystals were prepared by the Czochralski (Cz) method. Optical constants were measured. Chemical composition analysis and uniformity of scintillation decay and light yield along growth direction were evaluated. The timing resolution measurement for a pair of 3 mm×3 mm×3 mm size Ce:GAGG scintillator crystals was performed using Si-PMs.
