Item Reflectivity of VUV-sensitive silicon photomultipliers in liquid Xenon(IOP Publishing, 2021) Schneider, J.; Ziegler, T.; Wagenpfeil, M.Silicon photomultipliers are regarded as a very promising technology for nextgeneration, cutting-edge detectors for low-background experiments in particle physics. This work presents systematic reflectivity studies of Silicon Photomultipliers (SiPM) and other samples in liquid xenon at vacuum ultraviolet (VUV) wavelengths. A dedicated setup at the University of Münster has been used that allows to acquire angle-resolved reflection measurements of various samples immersed in liquid xenon with 0 45 angular resolution. Four samples are investigated in this work: one Hamamatsu VUV4 SiPM, one FBK VUV-HD SiPM, one FBK wafer sample and one Large-Area Avalanche Photodiode (LA-APD) from EXO-200.
