On Nov. 7, a Fermilab crew moved the cryostat vessel for the DUNE Near Detector Liquid Argon Demonstrator (DUNE ND-LAr) prototyping test stand, also known as ArgonCube 2×2, into the MINOS cavern 100 meters underground. From left to right: Matthew Brock, Thomas Olszanowski, John A. Trebe and Thomas Wicks II. Four prototype ArgonCube TPC modules will be installed in this cryostat in 2023. The prototype modules will undergo testing with the NuMI neutrino beam, powered by Fermilab’s Main Injector accelerator.
