Description
The Deep Underground Neutrino Experiment (DUNE) is an international collaboration focused on studying neutrino oscillation over a long baseline (1300 km). DUNE will make use of near and far detectors based on the LArTPC (Liquid Argon Time Projection Chamber) technology. The far detector site will be located 1.5 km underground at the Sanford Underground Research Facility in Lead, South Dakota. In order to make precise physics measurements at DUNE, such as the amount of CP violation in the neutrino sector, it is essential to be able to accurately reconstruct particle energies and other kinematic quantities; this in turn necessitates an extensive calibration program for DUNE’s LArTPC detectors. The far detectors will make use of designated calibration hardware as well as natural sources among which are cosmic ray muons. Due to the large depth of the far detector site, the rate of these muons in the detector will be relatively low (roughly 5000 muons passing the active volume per day). We will present a study of the potential to measure one of the detectors parameters, drift charge attenuation, in the horizontal-drift LArTPC modules using cosmic ray muons. We will focus on the achievable precision of measurements granular in time and within the detector volume.
