The DUNE experiment

Abstract The upcoming DUNE experiment heavily relies on Time Projection Chambers (TPCs) for their suitability for constructing large-scale detectors with excellent performance in tracking and energy reconstruction. DUNE will construct four 17 kton Far Detector Modules which will use Liquid Argon TPC technology. A R&D program is underway, testing at large-scales different designs of these detectors. The designs of the first two modules have been chosen, and detector construction is underway. The Near Detector comprises three components. A fixed on-axis detector, SAND, will monitor the beam. A large Liquid Argon TPC, NDLAr, serves to collect interactions with high statistics in a detector functionally similar to the Far Detectors whilst coping with the high interaction rate from the world’s most powerful neutrino beam. Downstream of NDLAr, The Muon Spectrometer (TMS), measures escaping muons. Both NDLAr and TMS can be moved up to 30m off-axis allowing to measure neutrino interactions at different beam energies. In Phase 2 of the experiment, DUNE will upgrade the Near Detector replacing TMS with a high performance gaseous argon TPC, NDGAr. In this article, the DUNE experiment is described and the construction status given.
