Abstract

In this report 2inch size Ce:Gd3Al2Ga 3O12 (Ce:GAGG) single crystals were grown by the Czhocralski (Cz) method. Luminescence and scintillation properties were measured. In order to determine light yield the energy spectra were collected under 662 keV γ-ray excitation(137Cs source) were detected by a APD S8664-55(Hamamatsu). The light yield of CeGAGG sample was calibrated from 55Fe direct irradiation peak to APD. The light yield was around 46,000photon/MeV. Energy resolution was 4.9%@662keV by using 3x3x1mm size sample. The density of CeGAGG is theoretically 6.63 g/cm3. Further results will be reported in the presentation.
