Description
Despite several advantages of Silicon Photomultipliers (SiPM) over Photomultiplier Tubes (PMT) like the increased photon detection efficiency (PDE), the compact design and the insensitivity to magnetic fields, the dark count rate (DCR) of SiPM is still a large drawback. Especially concerning applications with the need of large photosensitive areas or applications for which cooling of the detector is not an option. Reducing the dark count rate of SiPM would lead to an enormous enhancement of the application range of this promising photo-detector.
The main goal of this work is to gain initial information on dark generation and identify the dominating contributions to dark currents. The chosen approach to do so, is to extract characteristic activation energies of the contributing mechanisms from temperature dependent investigations of dark currents and DCR. In this talk, first steps towards the development of a reliable method for the analysis of dark currents and dark events are presented.
