Production and Testing of Scintillator Surface Detectors for the Pierre Auger Observatory in Aachen — •Julian Kemp, Thomas Bretz, Paulo Ferreira, Adrianna García, Thomas Hebbeker, Tobias Pan, and Christine Peters — III. Physikalisches Institut A, RWTH Aachen University

The Pierre Auger Observatory, located in the Argentinean Pampa, is a hybrid cosmic-ray detector measuring ultrahigh energy cosmic-ray air-showers. It consists of a surface array made up by 1660 water Cherenkov detectors which is overlooked by 27 fluorescence telescopes.

The Pierre Auger Observatory is currently undergoing a major upgrade, AugerPrime, to improve its performance. One main contribution is the installation of an additional scintillator detector on top of each surface detector station. It will allow for a more precise determination of air-shower characteristics, especially its number of muons.

The III. Physikalisches Institut A of the RWTH Aachen University is manufacturing and testing 135 of these Scintillator Surface Detectors. A procedure was developed to validate the performance of each detector individually before shipment.
