Long before the Deep Underground Neutrino Experiment takes its first measurements in an effort to expand our understanding of the universe, a prototype for one of the experiment’s detectors is blazing new trails in neutrino detection technology. DUNE, currently under construction, will be a massive experiment that spans more than 800 miles. A beam of neutrinos originating at Fermilab will pass through a particle detector located on the Fermilab site, then travel through the ground to a huge dete
