Abstract
Silicon photomultipliers are regarded as a very promising technology for nextgeneration, \ncutting-edge detectors for low-background experiments in particle physics. This work \npresents systematic reflectivity studies of Silicon Photomultipliers (SiPM) and other samples in \nliquid xenon at vacuum ultraviolet (VUV) wavelengths. A dedicated setup at the University of \nMünster has been used that allows to acquire angle-resolved reflection measurements of various \nsamples immersed in liquid xenon with 0 45 angular resolution. Four samples are investigated in \nthis work: one Hamamatsu VUV4 SiPM, one FBK VUV-HD SiPM, one FBK wafer sample and \none Large-Area Avalanche Photodiode (LA-APD) from EXO-200.
