Abstract

The Deep Underground Neutrino Experiment (DUNE) will be a world-class neutrino observatory and nucleon decay detector designed to answer fundamental questions about the nature of elementary particles and their role in the universe. The Collaboration will make use of the most intense neutrino beam ever operated, which will originate from the Fermi National Accelerator Laboratory (Chicago, US), it will propagate for about 1,300 km and will be detected by the far detector installed in the Sanford Underground Research Facility (SURF). The far detector will adopt the experimental technique of the Liquid Argon Time Projection Chambers (LArTPC) and will have a total active mass of 40,000 tons of liquid argon (LAr) segmented into four modules of about 10,00 tons each. The photon detection system of the DUNE far detector will be based on a device designed and developed in the São Paulo State, namely the X-ARAPUCA. This is a light trap which allows to reach an high photon detection efficiency even with a small coverage with active sensors (SiPM). It has been demonstrated during the protoDUNE run at CERN that this new device allows to increase the photon detection efficiency by a factor of ten with respect to existing technologies. (AU)
