Abstract :
In this work, energy resolution of Pr:LuAG scintillator was investigated using PMT (Hamamatsu, R7600U), conventional Si-APD (Hamamatsu, S8664-8222) and UV-enhanced Si-APD (Hamamatsu, S8664-8223) at 20°C by 662 keV gamma-ray irradiation. The APD S8664-8223 has better quantum efficiency (QE) of 45.8% around 310 nm of Pr:LuAG emission wavelength than that of S8664-8222 (QE=4.6%@310 nm) and R7600U (QE=21%@310 nm). Using UV-enhanced APD S8664-8223, Pr:LuAG sample with 2.15 × 2.15 × 10 mm size showed the best energy resolution of 5.7%@662 keV at M=10.7.
