Calibration of ProtoDUNE II Detectors

The ProtoDUNE detectors serve as prototypes for the Deep Underground Neutrino Experiment (DUNE) far detector, which utilizes Liquid Argon Time Projection Chamber (LArTPC) technology. DUNE will probe the neutrino mass ordering and CP violation in the lepton sector using the world's highest intensity neutrino beam. In LArTPCs, charged particles ionize a liquid argon medium; the resulting ionization electrons drift in an electric field to be collected on instrumented anodes on both sides of the detector. This process yields valuable information about particle trajectories and deposited energy. However, precise measurements are subject to uncertainties, making detector calibrations essential for the successful commissioning of the DUNE far detector. As detectors on the surface, the ProtoDUNE detectors can record a high flux of cosmic muons to be employed for calibration purposes. In this talk, calibrations using cosmic muons for the second round of DUNE far detector prototypes, ProtoDUNE II, are discussed.
