Abstract
The DUNE Photon Detection System (PDS) is based on a novel cryogenic light-detector called X-ARAPUCA. It downshifts the 127 nm Liquid Argon (LAr) scintillation light and employs a dichroic filter to trap photons inside a reflective box, which is instrumented with Silicon PhotoMultipliers (SiPM) arrays. In this paper, we present a brief overview of the design and performance of the X-ARAPUCA, in view of the Run II of ProtoDUNE-SP at CERN. Furthermore, two X-ARAPUCAs were employed in Run I to validate the effectiveness of xenon as a LAr dopant against the quenching effect of nitrogen impurities. Preliminary results of this special run are also presented.
