Strategic Plan
The proposed Long-Baseline Neutrino Experiment would greatly advance research at the Intensity Frontier. It is one of the top priorities identified by the P5 panel.

Neutrino Detectors
The LBNE Science Collaboration is advancing plans for a massive neutrino detector to find out whether neutrino interactions violate the matter-antimatter symmetry.

Neutrino Beam
Fermilab’s Main Injector produces the world’s highest-intensity neutrino beam. Scientists plan to send the beam to the proposed Sanford laboratory. Project X would dramatically increase the intensity of the neutrino beam and provide proton beams for other experiments, too.

LAr Cryostat Prototype
LBNE is constructing a 35-ton prototype cryostat for liquid argon. The cryostat construction uses commercial stainless-steel membrane technology engineered and produced by industry. These vessels are widely deployed in liquefied natural gas tanker ships, and are typically manufactured in sizes much larger than that proposed for the LBNE liquid argon Far Detector.
Neutrinos, astonishingly abundant yet not well understood, may provide the key to answering some of the most fundamental questions about the nature of our universe. The discovery that neutrinos are not massless, as previously thought, has opened a first crack in the highly successful Standard Model of Particle Physics. Neutrinos may play a key role in solving the mystery of how the universe came to consist only of matter rather than antimatter. Why neutrinos?
The proposed Long-Baseline Neutrino Experiment (LBNE) aims to precisely measure important properties of neutrinos in order to test our understanding of neutrinos and their role in the universe.
LBNE plans to send the world's highest-intensity neutrino beam hundreds of miles through the Earth's mantle to a large detector, a multi-kiloton volume of target material instrumented such that it can record interactions between neutrinos and the target material. The experiment will need to collect data for a decade or two since neutrinos interact so rarely. How does LBNE work?

LBNE Reconfiguration
Office of Science Director Bill Brinkman has charged Fermilab with finding a path forward to reach the scientific goals of the Long-Baseline Neutrino Experiment in a phased approach. A Steering Group has been formed by Fermilab to study phased approaches and alternative experimental configurations.
