Deep Underground Neutrino Experiment
The Deep Underground Neutrino Experiment (DUNE), formerly the Long Baseline Neutrino Experiment (LBNE), is a neutrino experiment with a near detector at Fermilab and a far detector at the Sanford Underground Research Facility that will observe neutrinos produced at Fermilab. It will fire an intense beam of trillions of neutrinos from a production facility at Fermilab (in Illinois) over a distance of 1,300 kilometers (810 mi) to an instrumented multi-kiloton volume of liquid argon located at the Sanford Lab in South Dakota. The proposed detector is to be about 12 meters (39 ft) across. Part of the path of the neutrinos would take them 30 kilometers (19 mi) underground (the beam itself will start 1.5 kilometers (4,900 ft) under the surface).

Funding and constructionEdit
The far detector current design is for four modules of instrumented liquid argon with a fiducial volume of 10 kilotons each. The first two modules are expected to be complete in 2024, with the beam operational in 2026. The final module is planned to be operational in 2027.
The Particle Physics Project Prioritization Panel (P5) concluded in its 2014 report that the research activity being pursued by LBNE "should be reformulated under the auspices of a new international collaboration, as an internationally coordinated and internationally funded program, with Fermilab as host". The LBNE collaboration was officially dissolved on January 30, 2015, shortly after the new collaboration recommended by P5 was formed on January 22, 2015. The new collaboration selected the name Deep Underground Neutrino Experiment (DUNE).
