Event Reconstruction with the Surface Scintillator Detectors of AugerPrime — Markus Roth1, •David Schmidt1, Alexander Streich1,2, Alvaro Taboada1,2, and Darko Veberic1 for the Pierre Auger collaboration — 1Karlsruher Institut für Technologie (KIT) — 2Universidad Nacional de San Martin (UNSAM)
Reconstructing the mass of ultra-high-energy cosmic rays from measurements performed at ground hinges on disentanglement of the electromagnetic and muonic components of extensive air showers. The AugerPrime upgrade to the Pierre Auger Observatory will do exactly this by equipping each of the existing water-Cherenkov detector stations in its surface detector array with a 4 m2 Scintillator Surface Detector, which is more sensitive to the electromagnetic component of showers. As part of the deployment plan, 77 detectors were switched on in March of 2019, and thousands of events have been collected since. We present the calibration of measurements performed by the upgraded stations as well as the first event reconstructions enhanced with information from the new detectors here.
