Evaluation of coincidence time resolution of YAG, LuAG, GAGG, YSO, LYSO, LSO, YAP and LuAP scintillators — •Dzmitry Kazlou, Valerii Dormenev, Kai-Thomas Brinkmann, Markus Moritz, Rainer Willi Novotny, and Hans-Georg Zaunick — 2nd Physics Institute, Justus Liebig University, Giessen, Germany

Development of new or optimization of already widely used scintillation materials for fast timing applications have become a very important research activity during the last decade. A significant progress with cerium doped inorganic materials has been made in the improvement of the timing characteristics of the scintillation pulse. Here we present test results of garnets YAG/LuAG/GAGG, lutetium-yttrium oxyorthosilicates YSO/LYSO/LSO and orthoaluminate perovskites YAP/LuAP with different types of doping. Samples have two types of dimensions: 3x3x3 and/or 3x3x20 mm³. The main activity was concentrated on the measurements of the coincidence time resolution (CTR) with the help of an oscilloscope by offline analysis of recorded signals and the dependence on temperature and the sample shape. Measurements were performed inside a climate camber and done with SiPM readout and commercial evaluation kits from different producers as well as with own developments.

The work was supported by funding from BMBF Projects 05K2019, UFaCal, EFRE, the High-D consortium and in the spirit of the Crystal Clear Collaboration.
