Megatile studies and development for the mass assembly of a highly granular hadron calorimeter — •Yong Liu for the CALICE-D collaboration — Institut für Physik, Johannes Gutenberg-Universtät Mainz, 55099 Mainz, Germany
A large 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. We have developed a novel design of scintillator tiles directly coupled to surface-mounted SiPMs, which addresses the challenge from automated mass assembly of around 8 million channels of the final HCAL detector. This design has been realized in 7 HCAL readout boards with a total of 1008 channels have been successfully built via mass assembly, and this design has been adopted as the baseline design for the large prototype construction. To further simplify mass assembly, various designs based on large scintillator plates with embedded structures for optical segementation ("megatiles") have been developed. Simulation studies as well as prototype developments and measurements will be presented in detail.
