The Deep Underground Neutrino Experiment (DUNE) is one of the most ambitious project in the actual experimental particle physics scenario. The far detector of the experiment will be constituted by a liquid argon time projection chamber with an active mass of 40 kton. The light detection system is a fundamental part of the detector and is used for triggering, time zero, particle identification and calorimetric purposes. At the moment the baseline option for the photon detection system of the DUNE far detector is based on the ARAPUCA concept. This is a light trap, which will allow to increase significantly the light detection efficiency of the detector with respect to the previous design based on scintillating/guiding bars. The present project is largely devoted to improve the ARAPUCA design with a smart and new light collection scheme which reduces the losses inside the reflective cavity. The newest design has been called X-ARAPUCA. It is proposed to perform great part of the R&D needed to optimize the proposed solution by installing an array of new generation X-ARAPUCA in the Short Baseline Neutrino Experiment which will be assembled at Fermi National Accelerator Laboratory starting from the next year and in the protoDUNE detector at CERN for its second run in 2021.
