We would like to appreciateY . Usuki (Furukawa Co.) for suggestive discussions, and H. Nagayama (Japan Atomic Research Institute), who conducted the 6oCo exposure. The present work is partly supported by a Grant-in-Aid from the Japanese Ministry of Education, Science and Culture, and by University of Tsukuba.

N2 - We have investigated applications of cerium-doped GSO (Gd2SiO5: Ce or GSO: Ce) scintillating crystals to high-precision electromagnetic calorimeters in high-energy physics experiments. Basic properties of GSO : Ce such as the decay time, light yield and radiation hardness were measured using small (∼4 cm long) sample crystals. The radiation hardness tests include the scintillator stability under 60Co exposure. The characteristics of the observed residual phosphorescence due to radiation were studied in detail. These properties are dependent on the Ce concentration. Between the two concentrations we tested, 0.5 and 1.5 mol%, GSO:Ce scintillator with 1.5 mol% Ce is better in various aspects. Recently, large ingots with 1.5mol% Ce concentration have been grown successfully. We report optical properties of 2.5 × 2.5 × 26 cm3 crystals. We discuss the feasibility of GSO : Ce scintillator-based calorimeters in operating under high radiation such as at future hadron collider experiments.
