Description
The Deep Underground Neutrino Experiment (DUNE), one of the future long-baseline neutrino experiments, is mainly devoted to investigate unequivocally the 3-neutrino oscillation parameter paradigm. Moreover, it has a broad physics program beyond long-baseline neutrino physics, encompassing Beyond Standard Model physics as well as a variety of non-accelerator searches, such as supernova neutrinos or nucleon decay.
DUNE will consist of the world’s most intense neutrino beam and two neutrino detectors. The Near Detector will be placed at Fermilab. The Far Detector will be located at the Sanford Underground Research Laboratory (SURF), 1300 km away. DUNE’s Far Detector is made of four independent underground modules based on the liquid argon time projection chamber (LArTPC) technology. The photon detection system (PDS) of the Far Detector is responsible for the detection of argon scintillation light, complementing the measurements performed by the TPC. The PDS is the main contribution of the DUNE-Spain’s groups toward the experiment’s construction.
In this talk I will discuss the critical role of the PDS toward DUNE’s physics in the areas of event $t_0$ reconstruction, calorimetry and triggering. I will also present the main R&D developments and ongoing optimizations concerning the PDS system, as well as its validation via the ProtoDUNE demonstrators at CERN.
