CERN, Fermilab, and SURF Begin Underground Construction of DUNE's Giant Neutrino Detector Cryostats

Construction has commenced on the two massive cryostat modules for the Deep Underground Neutrino Experiment (DUNE), nearly 1.5 kilometers below ground in South Dakota. Each cryostat will house approximately 17,000 tonnes of liquid argon at extremely low temperatures, with CERN contributing over 6,200 tonnes of steel and leading the cryostat design and installation. This marks a significant milestone for the international collaboration aimed at understanding neutrinos and fundamental questions about the Universe. Detector construction is anticipated to conclude by 2030, with Fermilab's neutrino beam expected to reach the detectors by 2031.
