  • Composition-property correlations have been systematically studied in the full concentration range of Y3Al5-xGaxO12:Ce (YAGG:Ce) scintillator crystals. The most promising compositions for new high energy physics experiments at colliders have been determined with the light output >200 % relatively to BGO and fast luminescence decay. Codoping with Ca2+ provides the decrease of phosphorescence intensity down to 0.2 % after 0.6 μs and shortening of luminescence decay constant to 21 ns. Factors affecting scintillation decay time in YAGG:Ce have been discussed. The crystals show weak transmission loss under γ-irradiation. A feasibility to produce YAGG:Ce fibers by the μ-PD method has been shown.Composition-property correlations have been systematically studied in the full concentration range of Y3Al5-xGaxO12:Ce (YAGG:Ce) scintillator crystals.
