The long-baseline Deep Underground Neutrino Experiment (DUNE) is a planned dual-site neutrino experiment projected to be in operation in 2022. This experiment will study high-energy neutrinos from a new, high-intensity neutrino beam (LBNF) generated by a megawatt-class proton accelerator at Fermilab, after propagating over a distance of 1,300 km to a far detector located deep underground at the Sanford Underground Research Facility in Lead, South Dakota. The far detector is a 40 kton LArTPC, and it will be the largest LArTPC to have ever been constructed.
DUNE at LBNF is a next-generation neutrino experiment planning to build a very large scale LArTPC (40 kton) to provide unprecedented sensitivity to leptonic CP violation and the neutrino mass hierarchy. The detector will be located at SURF at a baseline of 1,300 km from neutrino beam production at Fermilab. DUNE proposes an immense scientific program and will answer many of the great questions of neutrino physics.
DUNE's 1,300 km baseline delivers optimal sensitivity to neutrino charge-parity (CP) symmetry violation and neutrino mass ordering, via neutrino oscillation measurements. The combination of a massive fine-grained detector and underground detector placement also allows DUNE to study low-background physics, such as proton decay and neutrinos from supernova core collapse.
The DUNE physics program will address three of the top questions in particle physics: (1) What caused the preponderance of matter over antimatter in the early Universe? (2) What is the dynamics of supernova bursts that produced the heavy elements necessary for life? and (3) Do protons eventually decay?
Small Particles, Big Science: The International LBNF/DUNE Project
Neutrinos are the most abundant matter particles in the universe, yet very little is known about them. This animation shows how the Department of Energy’s Long-Baseline Neutrino Facility will power the Deep Underground Neutrino Experiment to help scientists understand the role neutrinos play in the universe. DUNE will also look for the birth of neutron stars and black holes by catching neutrinos from exploding stars. More than 800 scientists from 150 institutions in 27 countries are working on the LBNF/DUNE project, including Armenia, Belgium, Brazil, Bulgaria, Canada, Colombia, Czech Republic, Finland, France, Greece, India, Iran, Italy, Japan, Madagascar, Mexico, Netherlands, Peru, Poland, Romania, Russia, Spain, Switzerland, Turkey, Ukraine, United Kingdom, USA.
