Description
Observations at cosmological and astronomical scales indicate that the majority of matter in our Universe is in the form of non-relativistic and long-lived dark matter. Dual-phase xenon Time Projection Chambers (TPCs) are successfully operated in direct dark matter detection experiments. Silicon Photomultipliers (SiPM) are a favored candidate to detect the scintillation light in the next generation TPCs. Commercially available SiPMs do not fulfill all the requirements imposed by a dark matter detector, hence a dedicated development with the manufacturer is necessary. We present our dedicated low-temperature test facility, together with latest results on the temperature-dependent characterisation of SiPM arrays and optical photon simulations for a future SiPM-based TPC.
