Studies on 2015 testbeam data of a highly granular hadron calorimeter prototype — •Sascha Krause for the CALICE-D collaboration — Institut für Physik, Johannes Gutenberg-Universität Mainz, Germany

An Analog Hadronic Calorimeter (AHCAL) is being developed within the CALICE collaboration for the planned International Linear Collider (ILC). To achieve the required energy resolution for jets, the Particle Flow Algorithm has been proposed for the event reconstruction. One major requirement for this algorithm is a highly granular calorimeter. Therefore, about 8 million detector units consisting of scintillator tiles and silicon photomultipliers (SiPMs) will be installed in the final HCAL design. During a CERN SPS testbeam in 2015, data with a prototype consisting of up to 11 layers of HCAL Base Units (HBU) was collected using muon, electron and pion beams. A special feature was the first automatically assembled HBU including 144 scintillator tiles and surface mounted SiPMs. After several calibration steps and event selections, the testbeam data can be compared to a MC simulation of the prototype. First results of this comparison will be presented, testing the performance of the prototype.
