A SiPM-based scintillator prototype for the Upgrade of the Pierre Auger Observatory — •Johannes Schumacher, Thomas Bretz, Thomas Hebbeker, Julian Kemp, Rebecca Meissner, Lukas Middendorf, Tim Niggemann, and Christine Peters for the Pierre-Auger collaboration — III. Physikalisches Institut A, RWTH Aachen University, Germany
Plastic scintillator-based detectors are simple and yet powerful instruments, commonly used in particle physics experiments. These detectors are also planned to be installed at the Pierre Auger Observatory as part of the upgrade called AugerPrime. Here, a single detector module will consist of several large-sized scintillator bars. Embedded wavelength shifting fibres read out the scintillation light and are coupled to a single photo-sensitive device.
We investigate the application of silicon photomultipliers (SiPMs) in this scope, which benefits from high photon detection efficiency and stability. We show the performance of a SiPM-based prototype device installed in the 2 m2 detector ASCII - an early prototype of the scintillating detector planned for AugerPrime. We focus on the electronics, the optical coupling and the in situ calibration. As ASCII has been operating with SiPMs for several months now, we also highlight first high-energy events seen in coincidence with the Surface Detector of the Pierre Auger Observatory.
