Data acquisition for an SiPM based muon detector

To measure cosmic rays at the highest energies, ground based detectors sparsely covering an area of several thousand square kilometers to detect cosmic ray induced air showers are used. One of those experiments is the Pierre Auger Observatory, which is currently being upgraded for a better determination of the muonic component in the showers to allow a better identification of the type of primary particle. For this upgrade multiple different detector concepts and designs were proposed. One of those proposals is the Aachen Muon Detector (AMD), which is a tiled scintillator detector with silicon photomultipliers (SiPMs) as light sensors. To digitize the SiPM signals the EASIROC chip is used, which allows to read out 32 SiPMs and adjusting of their supply voltage with a low power consumption. The complete readout electronics, including the power supply unit as well as the firmware and software needed for operation, are described in this thesis. Furthermore, characterization measurements of the electronics and first measurements with the detector system are presented
