Progress in fast-timing Ce-doped garnet scintillators by complex codoping with divalent cations
Abstract
This work focuses on the development of fast-timing inorganic scintillators for use in cutting-edge particle physics experiments at colliders and time-of-flight positron emission tomography (TOF-PET). Significant progress in enhancing the timing performance of Y₃Al₅O₁₂ (YAG) scintillators is reported, achieved by optimizing the co-doping conditions with Ca²⁺ and Mg²⁺. The optimized crystals exhibit fast rise and decay times of 30 ps and 26 ns, respectively, alongside with an impressive coincidence time resolution (CTR) of 131 ps, while maintaining a high light output of over 22,000 pH/MeV. The incorporation of dopants into the YAG lattice is explored, providing insights into the mechanisms driving scintillation response in YAG:Ce,Ca,Mg crystals. Furthermore, uniformity in scintillation properties was demonstrated along a large, 120 mm-long YAG:Ce,Ca,Mg ingot, which was grown using the Czochralski method in a tungsten crucible.
