Description
The Deep Underground Neutrino Experiment (DUNE) aims to provide a broad physics program primarily focused on probing CP violation in the neutrino sector and determining the neutrino mass ordering. The experiment will consist of four far detectors, having a baseline technology of Liquid Argon Time Projection Chambers (LArTPCs) with 17 kton of liquid argon each. To successfully implement this detector, a prototype of one of the far detectors, the FD-HD, has been built at CERN to validate and commission the choices made for the final detector. The detector is the ProtoDUNE-HD, a LArTPC with 0.28 kton of liquid argon, featuring a horizontally applied electric field of 0.5 kV/cm and two drift regions. When a charged particle crosses the detector, it creates ionization electrons and scintillation photons at 128 nm. To read the charge signal, three wire planes (two induction and one collection) were implemented in the detector. Meanwhile, to read the photon signal, the X-ARAPUCA technology is used, which shifts the scintillation light to the visible region so it can be detected by Silicon Photomultipliers (SiPMs). The light signal plays a crucial role not only in improving energy resolution, but also in providing a trigger for non-beam events. In this presentation, the current status of the ProtoDUNE-HD photon detection system will be presented, including the status of the light yield, time resolution, and effects of varying the electric field strengths and other ongoing analyses.
