The DUNE Far Detector Interim Design Report Volume 1: Physics, Technology & Strategies Deep Underground Neutrino Experiment (DUNE)

Abstract

The Deep Underground Neutrino Experiment (DUNE) will be a world-class neutrino observatory and nucleon decay detector designed to answer fundamental questions about the nature of elemen tary particles and their role in the universe. The international DUNE experiment, hosted by the U.S. Department of Energy’s Fermilab, will consist of a far detector to be located about 1.5 km underground at the Sanford Underground Research Facility (SURF) in South Dakota, USA, at a distance of 1300 km from Fermilab, and a near detector to be located at Fermilab in Illinois. The far detector will be a very large, modular liquid argon time-projection chamber (LArTPC) with a 40 kt (40 Gg) fiducial mass. This LAr technology will make it possible to reconstruct neutrino interactions with image-like precision and unprecedented resolution.
