Performance and Calibration of the Upgraded Surface Detector of the Pierre Auger Observatory — •Alexander Streich, David Schmidt, Darko Veberic, Markus Roth, and Ralph Engel for the Pierre Auger collaboration — Karlsruher Institut für Technologie (KIT), Karlsruhe, Deutschland

The AugerPrime upgrade defines the transition to the next measurement stage of the Pierre Auger Observatory and is rolled out among other things with the addition of new scintillation detectors on top of the water-Cherenkov detectors of the Surface Detector. These Surface Scintillator Detectors provide a complementary measurement of the secondary particles enabling the discrimination of the individual air shower components on an event-to-event basis. This leads to an significantly improved determination of the properties of the ultra-high energy cosmic rays, for example their mass composition. Besides the scintillation detectors, the electronics boards of each station will be replaced with an enhanced version with an increased signal resolution, a higher sampling frequency, as well as faster data processing. This presentation focuses on the analyses of the performance of these hardware components under the measurement conditions in the Observatory. Thereby, the general operation stability and hardware requirements are investigated. Additionally, the performance of the air shower reconstruction applied to the first array of AugerPrime stations is analyzed, including the necessary adaptations to the detector calibration procedure and the signal discrimination capability of the hybrid event detection utilizing the scintillation and Cherenkov detectors.
