Description
The Deep Underground Neutrino Experiment (DUNE) is a next-generation international experiment that aims to advance our understanding of neutrinos. By combining a powerful wide-band neutrino beam and a high-performance Near Detector complex at Fermilab with a massive Far Detector (FD) located 1300 km away at the Sanford Underground Research Facility (SURF), DUNE will be able to determine the neutrino mass ordering, measure potential CP violation in the lepton sector, and test the completeness of the three-flavor paradigm.
In particular, the FD will consist of four large Liquid Argon Time Projection Chambers (LArTPCs), equipped with a novel Photon Detection System (PDS), capable of detecting liquid argon scintillation light at 128 nm with optimal efficiency and large-area coverage at a reasonable cost. This poster focuses on the R&D and characterization efforts led by the Institute of Corpuscular Physics (IFIC - Valencia) within the DUNE PDS consortium. It will be presented several optical measurements, including transmittance and reflectivity studies of key detector materials, as well as photon collectors performance evaluation. These results are fundamental for maximizing light collection efficiency and timing resolution, ultimately ensuring the physics goals of the DUNE program.
