The global neutrino physics community is coming together to develop a leading-edge, dual-site experiment for neutrino science and proton decay studies, hosted at Fermilab in Batavia, IL.
The facility required for this experiment, the Long-Baseline Neutrino Facility (LBNF), will be an internationally designed, coordinated and funded program, comprising the world's highest-intensity neutrino beam at Fermilab and the infrastructure necessary to support massive, cryogenic far detectors installed deep underground at the Sanford Underground Research Facility (SURF), 800 miles (1,300 km) downstream, in Lead, SD.
LBNF is also responsible for the facilities to house the experiment's near detectors on the Fermilab site.
LBNF will be tightly coordinated with the DUNE collaboration designing the detectors that will carry out its experimental program.
Neutrinos created by the LBNF beamline will travel 1,300 km (800 mi) to intercept DUNE's massive, cutting-edge neutrino detector at the Sanford Lab. The neutrino beam’s path will lead straight through the earth's mantle. Neutrinos pass easily through soil and rock — or kilometers of solid lead, for that matter — rarely interacting with the matter. No tunnel is needed for these ghostly particles.
