The DUNE (Deep Underground Neutrino Experiment) is made of two massive neutrino detectors 1300 km (800 miles) apart, one at Fermilab in Illinois and one at the Sanford Underground Research Facility in South Dakota. The near detector in Illinois will be 60 meters (200 feet) underground. The far detector modules will be 1.5km (about a mile) underground at the Sanford lab.
Neutrinos are also called ghost particles, they go through almost everything unnoticed and move at almost the speed of light. There are three types of neutrinos: electron, muon, and tau. The near detector will show neutrino beams right after their creation which will allow scientists to search for new particles and subatomic phenomena. After the neutrinos are through the near detector they will turn into one of those three types. The far detector will be the most technologically advanced and largest liquid argon detector holding 70,000 tons of liquid argon and being 20 times larger than other detectors of this kind.
During the DUNE experiment we hope to learn more about the origin of matter and if neutrinos are the reason everything is made of matter instead of anti-matter. We also hope to learn more about proton decay and perhaps see the birth of a neutron star or black hole. There are over 1,000 scientists all over the world collaborating on this experiment.
