The fundamental questions refer to the origin and the acceleration mechanisms of cosmic rays specifically at the highest energies. To address these questions, it is of paramount importance to study the composition of ultra-high energy cosmic rays (UHECRs).The Pierre Auger Observatory in Argentina pursues this objective with its upgrade AugerPrime. Within this scope, this thesis introduces silicon photomultipliers (SiPMs) to boost the performance of two detector subsystems of AugerPrime: The Surface Scintillation Detector (SSD) and the First Auger Multi-pixel photon counter camera for the Observation of Ultra-high energy cosmic air Showers (FAMOUS).While the first chapters of this thesis deal with ultra-high energy cosmic ray (UHECR) detector projects like the Pierre Auger Observatory and its upgrade (chapter 2 and 3), the following chapter introduces intrinsic parameters of SiPMs and standard calibration routines (chapter 4). These devices and their characteristics are of fundamental importance for the work that follows. A large-sized SiPM was used to replace a standard vacuum photomultiplier tube (PMT) in the prototype surface scintillation detector – Auger Scintillators for Composition – II (ASCII) – the predecessor of SSD. It is shown that SiPMs offer great intrinsic calibration capabilities that allow in-situ calibration of the scintillator, out-performing PMTs easily. Due to its splendid performance, the concept was adapted to SSD which is introduced afterward (chapter 5). The idea to build a small-sized SiPM-based telescope came up in the early 2010s. The work of this thesis focusses on the electronics, its calibration, and the first high-energy events. This is discussed in the last chapter (chapter 6). With its intelligent biasing and triggering system, as well as its mechanical and electrical robustness, the design of the FAMOUS telescope was duplicated and introduced in different astroparticle physics applications which will be summarized at the end of this thesis. This work concludes with a summary and a quick glance into the future. Published by Aachen |
