    The LBNE Science Collaboration

    As of April 2014, more than 485 scientists and engineers from more than 80 institutions participate in the LBNE Science Collaboration, led by cospokespersons Bob Wilson (CSU) and Milind Diwan (BNL). The collaborators come from universities and national laboratories, including collaborators from the United States, India, Italy, Japan, Brazil and the UK.

    Progress on Prototype Cryostat

    A 35-ton prototype cryostat has demonstrated that a non-evacuable "membrane" cryostat, the type chosen for the LBNE far detector, can satisfy the liquid argon purity requirement. A second phase of testing, currently in preparation, will focus on the performance of the active detector elements. In the image, the pvc frame represents the interior of the cryostat; it will be used to mock up the installation of the detector components prior to bringing them to Fermilab.

  • 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. A planned accelerator upgrade, called PIP-II, would dramatically increase the intensity of the neutrino beam and provide proton beams for other experiments, too.

Over 485 people from over 80 institutions participate in the Long-Baseline Neutrino Experiment (LBNE), working together to plan and develop both the experimental facilities and the physics program. LBNE is expected to be fully constructed and ready for operations in 2022. New collaborators are welcome.

LBNE plans a world-class program in neutrino physics that will measure fundamental physical parameters to high precision and explore physics beyond the Standard Model. The measurements LBNE makes will greatly increase our understanding of neutrinos and their role in the universe, thereby better elucidating the nature of matter and antimatter.

How will LBNE work?
LBNE will send the world's highest-intensity neutrino beam 800 miles through the Earth's mantle to a large detector, a multi-kiloton volume of liquid argon instrumented such that it can record interactions between neutrinos and this target material. Neutrinos are harmless and can pass right through matter, only very rarely colliding with other matter particles. Therefore, no tunnel is needed; the vast majority of the neutrinos will pass through the mantle's material, and in turn, right through the detector. Because neutrinos interact so rarely, the experiment will need to collect data for a decade or two in order to observe enough interactions to achieve its scientific objectives.

Fermilab, in Batavia, IL, is the host laboratory and the site of LBNE's future beamline, and the Sanford Underground Research Facility, in Lead, SD, is the site selected to house the massive far detector. The term "baseline" refers to the distance between the neutrino source and the detector.

Why neutrinos?
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.
