A prototype neutrino detector made up of these large panels built at UW–Madison’s Physical Sciences Laboratory recently “saw” its first particles at the international particle physics lab CERN in Switzerland. The panels are integral to development of a large detector that will be installed deep within a South Dakota mine in the 2020s to get a clearer look at neutrinos — the universe’s most abundant, but little understood, bits of matter.
