Utilization of fast and efficient scintillating materials for radiation detectors has played a crucial role in the discovery of the properties of matter in the last decades. However, the operation in a harsh radiation environment generated at high intensity machines such as the LHC and FAIR demonstrated their limitations and underlined the requirements for materials more tolerable to radiation damage in particular caused by high energy hadrons. Glass and glass ceramics can be considered as alternatives to crystal-based scintillators. Here we report on the performance of a low cost glass (BaO*2SiO2) and the glass ceramics DSB: Ce/Gd and in addition on aspects of industrial mass production. Admixing gadolinium oxide (Gd3+) even provides up to five times larger light yield. This work summarizes the present status of the overall performance of small and large samples.
The work was supported by funding of EU Horizon 2020 under Grant Agreement No 777222 (ATTRACT) and No 654002 (INTELUM), BMBF Project 05K2019 - UFaCal and in the spirit of the Crystal Clear Collaboration.
