Abstract

In this paper results of gamma spectroscopy with the GAGG: 1%Ce scintillators with different Al-to-Ga ratio are showed. The study covered measurements of emission spectra, light output, energy resolution and non-proportionality for each crystal. It was observed that the light output of the recent set of scintillators was significantly improved in comparison to the previous set and varies from 40000 to 55000 ph/MeV. The best energy resolution of 3.7% at 662 keV was obtained using a Hamamatsu S8664-1010 avalanche photodiode. This result can be compared to scintillators possessing very good energy resolution, like LaCl3 and CeBr3.
