AugerPrime scintillator simulations for the Pierre Auger Observatory — •David Schmidt, Matthias Kessler, Alvaro Taboada, Darko Veberic, and Markus Roth for the Pierre Auger collaboration — Karlsruhe Institute of Technology, Karlsruhe, Germany
Measurement of both the primary energy and muon content of extensive air showers is integral to reconstructing the mass of ultra-high-energy cosmic rays on an event-by-event basis. The Pierre Auger Observatory is currently upgrading its surface array by placing a 4 m2 scintillator on top of each of the existing 1660 water Cherenkov detectors. In tandem, the two sub-detectors provide the necessary information to disentangle and accurately reconstruct the muonic and electromagnetic shower components, which allows for reconstruction of primary mass. Prior to deployment, the responses of 12 prototype scintillator detectors were measured using a muon telescope of the KASCADE experiment. In turn, these measurements were used for tuning Geant4 simulations implemented inside the Offline shower reconstruction software. Photoelectron signal and timing models derived from prototype measurements, their implementation in simulations, and comparisons between the simulations and muon telescope measurements are presented here.
