Early tests pave the way for a giant neutrino detector
An enormous future particle detector is now within closer reach. The first data from a prototype experiment hint that scientists may have what it takes to build the planned neutrino detector. Known as the Deep Underground Neutrino Experiment, or DUNE, the experiment will use 70,000 metric tons of liquefied argon to study the secrets of these neutrinos — bizarre, nearly massless particles that may help reveal why matter is common in the universe but antimatter is rare. DUNE will eventually detect the tracks of charged particles, including electrons and their heavier cousins, muons, that are produced when neutrinos interact.
