Evaluation of Scintillator Tiles and SiPMs for highly granular Calorimeters — •Malinda de Silva, Frank Simon, and Marco Szalay — Max-Planck-Institut für Physik, Föhringer Ring 6, 80805 München

Plastic scintillator tiles and Silicon photomultipliers (SiPMs) are key elements of highly granular imaging calorimeters being developed for HL-LHC upgrades and for experiments at future colliders and in neutrino beams. The light yield of the combination of the scintillator and the SiPM, as well as the spatial response uniformity of the scintillator elements, are crucial for the overall performance of the detectors. In this contribution we discuss detailed studies of different scintillator tile geometries and other scintillator elements, performed with a uniformity scanning setup based on a radioactive source, as well as the observed light yield of tiles obtained with standard and with high dynamic range Hamamatsu MPPCs.
