Studies on scintillator tiles and surface-mounted SiPMs for the mass assembly of a highly granular hadron calorimeter — •Yong Liu for the CALICE-D collaboration — Institut für Physik, Johannes Gutenberg-Universität Mainz, Mainz, Germany

A technological prototype of a highly granular sampling hadron calorimeter (HCAL) based on scintillator tiles and silicon photomultipliers (SiPMs) is being developed within the CALICE collaboration. Driven by the need of an automated mass assembly of around 8 million channels of the final HCAL, we developed a design of scintillator tiles directly coupled to surface-mounted SiPMs and successfully built an HCAL readout unit with 144 channels via mass assembly. Results of extensive performance tests will be shown. Further studies on the characterisation of a novel SiPM with extremely low noise as well as tile design optimisations for the next generation of HCAL readout units will also be presented.
