Simulation and analysis of surface scintillator signals at the Pierre Auger Observatory — •David Schmidt, Darko Veberic, and Markus Roth for the Pierre-Auger collaboration — Karlsruhe Institute of Technology, Karlsruhe, Germany

To improve reconstruction of cosmic ray primary mass, the Pierre Auger Observatory is upgrading its surface detectors by installing a scintillator on top of each existing water Cherenkov tank. The different responses of the coupled detectors to the components of extensive air showers facilitates estimation of the number of muons reaching Earth's surface, which is correlated with primary mass. Geant4 and the Offline framework are used to simulate the detectors' responses, construct signal traces for individual particle components, and calculate total expected signals. This enables assessment of proposed reconstruction algorithms. An overview of the simulations and selected algorithms is presented here.
