Analysis of an Integrated Readout Layer for use in a Highly Granular Analog Hadron Calorimeter The International Linear Collider requires high granularity calorimetry to reach the performance benchmarks necessary for the physics it intends to measure. The leading option for achieving this granularity in the hadron calorimeter are 3 cm x 3 cm scintillator tiles mated to Silicon Photomultipliers. This thesis reviews the design, assembly and performance of an integrated readout layer (IRL) in the form of a 9x11 scintillator megatile directly coupled to silicon photomultipliers (SiPM). The IRL performance in terms of response and efficiency and optical crosstalk is studied using both a ⁹⁰Sr source and test beam runs. The muon data used in this study was collected at the November 2014 CERN SPS test beam conducted by the CALICE collaboration. Along with the results, analysis tools like the event framework developed as well as algorithms for finding tracks and crosstalk are described.
