Excavation of underground caverns for DUNE halfway complete

Deep below the surface in South Dakota, US, construction crews have been working to carve out a network of caverns and tunnels that one day will house a huge neutrino experiment. Their efforts are paying off with almost 400,000t of rock extracted from the earth, the excavation is now half complete.

Almost 800,000t of rock need to be excavated to create the space for the South Dakota portion of the Deep Underground Neutrino Experiment

Once finished, the Long-Baseline Neutrino Facility (LBNF) will be the site of the international Deep Underground Neutrino Experiment (DUNE).
