"Deep Underground: Massive Caverns Prepared for Neutrino Experiment"

Three massive caverns, equivalent to eight soccer fields in size, have been excavated 4,800 feet below the surface in South Dakota to host the Deep Underground Neutrino Experiment (DUNE). The experiment, supported by the US Department of Energy’s Fermi National Accelerator Laboratory, aims to study the behavior of neutrinos to address fundamental questions about the universe. The caverns will house four large neutrino detectors, each the size of a seven-story building, and the first detector is expected to be operational by the end of 2028. The DUNE collaboration, involving over 1,400 scientists and engineers from 36 countries, has begun mass production of detector components and is conducting technology testing at CERN.
