Prototype detectors for the Deep Underground Neutrino Experiment

The international Deep Underground Neutrino Experiment, hosted by Fermilab, will investigate the role neutrinos play in the universe. To test the technologies used by DUNE, scientists are building two large prototype detectors at CERN. Filled with 800 tons of liquid argon, the ProtoDUNE detectors are the largest particle detectors of their kind. The actual DUNE detector modules, which will be assembled 1.5 kilometers underground at the Sanford Underground Research Facility, will be 20 times bigger than these test beds. More than 1,000 scientists from research institutions in 32 countries are working on DUNE.

On Sept. 18, 2018, DUNE scientists announced the observation of the first particle tracks with the first of the two prototype detectors:
