Description
The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino oscillation experiment designed with a wideband beam to precisely measure oscillation parameters, aiming to determine neutrino mass ordering with very high significance and explore Charge-Parity (CP) violation. The experiment will also have sensitivity to investigate new physics Beyond the Standard Model (BSM) and detect astrophysical neutrinos from supernovae and the Sun.
The DUNE Far Detector will employ advanced Liquid Argon Time Projection Chamber (LArTPC) technology, augmented by a Photon Detection System (PDS) based on X-ARAPUCA — a novel device with highly reflective internal surfaces and an internal photon guide that increases the probability of collecting trapped photons onto a silicon photomultiplier array.
To validate the performance of full-scale detector components, the ProtoDUNE-Horizontal Drift (HD) prototype, a 750-ton LArTPC, was built at CERN and collected data from April to November 2024.This work presents new results from X-ARAPUCA efficiency in the ProtoDUNE-HD using particles from the CERN beamline, with a joint data and MC simulation analysis. Simulations were performed with the Liquid Argon Software (LArSoft) framework employing a semi-analytical photon propagation model to characterize the DUNE PDS response.
These results open new opportunities to improve neutrino detection and reconstruction in DUNE.
