The Deep Underground Neutrino Experiment (DUNE) is a leading-edge,
international experiment for neutrino science and proton decay studies.
Discoveries over the past half-century have put neutrinos, the most abundant
matter particles in the universe, in the spotlight for further research into
several fundamental questions about the nature of matter and the evolution of
the universe — questions that DUNE will seek to answer.

DUNE will consist of two neutrino detectors placed in the world’s most intense
neutrino beam. One detector will record particle interactions near the source
of the beam, at the Fermi National Accelerator Laboratory in Batavia, Illinois.
A second, much larger, detector will be installed more than a kilometer
underground at the Sanford Underground Research Laboratory in Lead, South
Dakota — 1,300 kilometers downstream of the source. These detectors will
enable scientists to search for new subatomic phenomena and potentially
transform our understanding of neutrinos and their role in the universe.

LBNF provides the enormous caverns and cryogenics infrastructure for the DUNE
detector deep underground at Sanford Lab. This includes the excavation of
800,000 tons of rock. It will also build structures at Fermilab to send
neutrinos through stone and earth to South Dakota — no tunnel needed.
