Test Beam Performance and Detailed Studies of the Structure of Hadronic Showers with Highly Granular Calorimeters

Abstract : The highly granular calorimeters developed and tested by the CALICE collaboration have provided large data samples with precise three-dimensional information on hadronic showers with steel and tungsten absorbers and silicon, scintillator and gas detector readout. We will discuss the performance of the RPC-based Semi-Digital Hadron Calorimeter in terms of energy resolution and pattern recognition, compared to Geant4 based simulations including a detailed modeling of the RPC response. The influence of granularity on the resolution obtained with digital, semi-digital and analog reconstruction method will be demonstrated based on the analogue HCAL data and simulations. We will also present the results of the performance studies of the combined scintillator-based calorimeter system (Sc-W ECAL, Sc-Fe AHCAL and Sc-Fe TCMT). The validation of the system with muons and electrons will be discussed as well as the single hadron energy resolution using both classical energy reconstruction and software compensation techniques in comparison with the predictions of Geant4 simulations. We will show the parametrisation of the radial development of hadronic showers in the Sc-Fe AHCAL and the progress in the predictions of several Geant4 physics lists. The results of the detailed measurement of hadronic showers in the SiW ECAL in terms of integral observables will be also presented; the observables, which characterise the interaction region and tracks produced by secondaries will be analyzed and compared to Geant4 simulations.
