Description
Vacuum ultraviolet (VUV) photon detection for large cryogenic liquid detectors such as DUNE is challenging because photosensors are typically not sensitive to VUV light, while large detection areas are required in limited available space. X-ARAPUCAs are light traps that shift VUV photons to wavelengths around 400 nm and confine the light for detection by silicon photomultipliers (SiPMs). At CIEMAT, we have developed setups to characterize SiPMs, assemble X-ARAPUCA modules, and measure the absolute photon detection efficiency for different X-ARAPUCA configurations.
