* Silicon Photomultiplier KIT
The Silicon Photomultipliers (SiPM) consist of a high density (up to ~ 103/mm2) matrix of photodiodes with a common output. Each diode is operated in a limited Geiger-Müller regime, in order to achieve gain at the level of 106. As a consequence these detectors are sensitive to single photons (even at room temperature), feature a dynamic range well above 100 photons/burst and have reasonable photon detection efficiency (PDE). Compactness, robustness, low cost, low operating voltage and power consumption represent the advantages over traditional photodetectors.
