Single crystals of Gd 3 Ga 3 Al 2 O 12 :Ce with B codopants were successfully grown using the Czochralski technique. The timing characteristics of the crystal was measured by coupling the crystal to photomultiplier tubes (PMT) or silicon photodiodes [Si(PIN)]. The two prompt γ‐rays emitted in a cascade from 60 Co or 22 Na source were detected in coincidence using Gd 3 Ga 3 Al 2 O 12 :Ce,B crystal detectors and a BaF 2 detector. The time resolution of these crystals are observed to be better than that measured for CsI:Tl crystal coupled to PMT or Si(PIN) in an identical measurement setup.
