摘要

We study the decay time constants and light output of an 18× 18× 1 mm3 YAIO3 crystal doped with cerium. Theresult shows that the light pulse is composed of fast and slow components. The fast component has a decay timeconstant of 24.05:+-0.15 ns with an intensity of 81.57±0.97% and the slow component has a decay time constantof 87.67±2.49ns with an intensity of 18.51±1.34%. The measured light output is 3608±80 photoelectrons/MeVwithout the correction for the quantum efficiency of the photomultiplier tube XP2262B.
