Status of the NDLAr 2x2 prototype for the Deep Underground Neutrino Experiment (DUNE)

The Deep Underground Neutrino Experiment (DUNE) is a future-generation, long-baseline neutrino experiment. Crucial to its performance for studying long-baseline oscillation physics is the near detector complex, which will be used to characterise the outgoing neutrino beam. One of DUNE's near detectors, NDLAr, exploits the same nuclear target and operational principles as the far detector, which is critical for constraining systematic uncertainties. Mitigation of high event pileup from the world's most intense neutrino beam will be facilitated by a modularised detector design. NDLAr will also employ state-of-the-art charge and light readout technologies. The novel pixelated charge readout based on LArPix will enable true 3D readout of the events, eliminating ambiguity that arises with conventional wire readout LArTPCs. The collection of scintillation light will be facilitated through two functionally identical, SiPM-based, and complimentary light trapping systems, called Light Collection Modules (LCMs) and ArCLights. which will provide both high light yield and position resolution. This talk will focus on the DUNE NDLAr 2x2, a prototype of NDLAr containing 4 individual LArTPC modules, outlining on the testing and performance up to date as well as physics goals.
