The SiPM board is a printed circuit board (PCB) designed to dock and process the signal from the SiPM-scintillator coupling into a readout. Ideally no information such as timing from the scintillator should be lost, and the signal could be amplified/ processed with the board. In some applications involving significant temperature fluctuations, a compensator could also be built into the board. For the Muonpi project, the board should just be able to dock the SiPM-scintillator coupling to the readout.

The circuit configuration of the PCB varies depending on the number of SiPM's it needs to accommodate. For housing a single SiPM the configuration is to just connect it with ground and readout/ bias. However, for connecting multiple SiPM's there are two possible configurations: parallel (p) and hybrid (h) configuration as illustrated below.

Both configurations are quite similar in term of performance, with the hybrid configuration having a slightly faster rising edge (by a few ns <ref>[Nies, L., Zaunick, H. G., & Brinkmann, K-. T.. Development of a SiPM-based readout-module for the characterization of various scintillator materials. arXiv. (2018). </ref>). The signal amplitude for the hybrid configuration decreases by a factor of <math>\frac{1}{\sqrt{N}}</math> where N the number of SiPM, whereas the signal amplitude does not change for parallel configuration. However, the timing of the parallel configuration also decreases with the number of connected SiPM's; hence, for applications that are very time sensitive, the hybrid configuration might be necessary. Moreover, the hybrid configuration has more complexity, which might make the configuration more expensive to produce. Therefore for simplicity, the Muonpi project uses the parallel configuration. It keeps the simplicity while giving the option for adding SiPM further down the road. The schematic of the SiPM board for the Muon Pi project is shown below.

+Die SiPM-Platine ist eine Leiterplatte (PCB), die dazu dient, das Signal der SiPM-Szintillator-Kopplung anzudocken und in eine Auslesung zu verarbeiten. Idealerweise sollten keine Informationen wie z. B. das Timing vom Szintillator verloren gehen, und das Signal könnte mit der Platine verstärkt/verarbeitet werden. Bei einigen Anwendungen, bei denen erhebliche Temperaturschwankungen auftreten, könnte auch ein Kompensator in die Platine eingebaut werden. Für das Muonpi-Projekt sollte das Board lediglich in der Lage sein, die SiPM-Szintillator-Kopplung an die Auslesung anzudocken.

+Beide Konfigurationen sind in Bezug auf die Leistung recht ähnlich, wobei die Hybridkonfiguration eine etwas schnellere steigende Flanke aufweist (um einige ns <ref>[Nies, L., Zaunick, H. G., & Brinkmann, K-. T.. Development of a SiPM-based readout-module for the characterization of various scintillator materials. arXiv. (2018). </ref>). Die Signalamplitude für die Hybridkonfiguration verringert sich um den Faktor <math>\frac{1}{\sqrt{N}}</math> wobei N die Anzahl der SiPMs ist, während sich die Signalamplitude bei paralleler Konfiguration nicht ändert. Allerdings sinkt auch das Timing der parallelen Konfiguration mit der Anzahl der angeschlossenen SiPMs; daher könnte für Anwendungen, die sehr zeitempfindlich sind, die Hybridkonfiguration erforderlich sein. Außerdem ist die Hybridkonfiguration komplexer, was die Herstellung der Konfiguration teurer machen könnte. Der Einfachheit halber verwendet das Muonpi-Projekt daher die parallele Konfiguration. Dadurch bleibt die Einfachheit erhalten, während die Option besteht, SiPM später hinzuzufügen. Der Schaltplan der SiPM-Platine für das Muon Pi-Projekt ist unten abgebildet.
