Description
The Deep Underground Neutrino Experiment (DUNE) will be using a liquid argon time projection chamber (LAr TPC) with optically separated modules in the Near Detector (ND) complex. A prototype experiment for these modules, DUNE ND-LAr 2x2, is currently commissioning and constructing four test modules. These modules detect ionization charge through a pixel-based readout and scintillation light through fibers in Light Collection Modules and light traps called ArCLights. This presentation will discuss the light detection performance for two modules of DUNE ND-LAr 2x2 that took cosmic ray data at the University of Bern. The talk will discuss the role of DUNE ND-LAr 2x2 in DUNE and the reconstruction capabilities of its light detectors in terms of energy thresholds and timing resolution.
