摘要：

Scintillation properties of Ce-doped (La, Gd)(2)Si2O7 (Ce:La-GPS) crystal were measured with Si avalanche photodiode (APD, Hamamatsu S8664-55). Since Ce:La-GPS is a novel scintillator, its scintillation properties have been evaluated using the APD for the first time. This crystal grown by floating zone method had a good light output of 41,000 +/- 1000 photons/MeV and FWHM energy resolution at 662 keV was 4.4 +/- 0.1% at 23.0 +/- 0.2 degrees C. The photon non-proportional response (PNR) of Ce:La-GPS was approximately 65% at 32 keV, where light output at 662 key was normalized to 100%. Moreover, the temperature dependence of the light outputs was determined to be approximately 0.15%/degrees C from 10 to 30 degrees C. (C) 2014 Elsevier B.V. All rights reserved.
