Photon Detectors for the DUNE Vertical Drift Module-0

The Deep Underground Neutrino Experiment (DUNE) will use an intense neutrino beam starting from Fermilab (Chicago) with a Near Detector to monitor the beam and a Far Detector installed in the Sanford Underground Research Facility (SURF - South Dakota), 1300 km far away. Four 17 kt Liquid Argon Time Projection Chambers (LArTPC) will compose the Far Detector to measure and reconstruct neutrino interactions using charge and light signals from ionizing radiation. The second of the four LArTPC modules (Vertical Drift) will detect photons with the X-ARAPUCA detector concept. A full-scale prototype ("Module-0") is being constructed for testing at the CERN Neutrino Platform in the coming year. The concept, construction, and expected performance of the X-ARAPUCA detectors for Module-0 will be presented.
