Abstract
The Deep Underground Neutrino Experiment (DUNE) will be using optically separated liquid
argon time projection chambers in the Near Detector (ND) complex to cope with the high event
pile-up. DUNE ND-LAr 2x2 (ProtoDUNE-ND) is a prototype experiment for these modules. The
capabilities of this detector, including the performance of the charge and light readout systems,
the signal matching between the two, the detector purity, and the response uniformity, have been
demonstrated with two ton-scale prototypes operated at the University of Bern. They acquired
large samples of cosmic ray data by detecting ionization charge through a true 3D pixel-based
charge readout and scintillation light through advanced high-coverage photon detection systems,
the Light Collection Modules (LCM) and the light traps called ArCLights. The main results from
the analysis of these data sets, as well as the overall status of the ND-LAr detector and the role of
ProtoDUNE-ND in DUNE, are presented in this poster.
