In recent years, Silicon Photomultipliers (SiPMs) developed into mature photon detectors which are chosen in a wide field of applications. However, the dark count rate (DCR) of SiPMs sets strong limitations to such detector systems. This quantity describes the rate at which pulses are generated in the absence of light (dark pulses) and deteriorate the photon counting performance of SiPMs. In the course of the presented research, two innovative characterization...
