Paper Abstract

The properties of high rare-earth-containing germanate glass have been investigated to assess the potential for using this material to construct electromagnetic calorimeters for particle physics. We report here on measurements of scintillation yield, transmission and decay time, on large blocks of Ce3+-doped Gd2O3-based glasses, the samples were excited by a high energy X-ray beam and the associated scintillation yield and decay time was measured. The optical transmission of the samples was measured. It was observed that scintillation yield of present scintillation glass is 20 - 30% of BGO scintillation yield, decay time is in range of 60 - 90 ns, glass density is 5.75 g/cm3. It was concluded that higher density and availability and low cost make this glass become promising candidate for cerium doped dense scintillator.
