The LBNE far detector will require a cryostat to hold between 5,000 and 17,000 tons of liquid argon at 89 K – a significantly larger volume than any existing liquid-argon detector. The LBNE project team is currently constructing a 35-ton-capacity prototype cryostat at PPD’s PC-4 facility…

The selected beamline design details a proton beam, above ground level, running through a hill and to a ground-level target. As the Long-Baseline Neutrino Experiment (LBNE) moves closer to its CD-1 review this coming spring, the project team has steadily honed its conceptual design to reduce cost while maintaining necessary functionality and safety features. The LBNE team plans to construct a beamline and near detector at Fermilab and a neutrino detector 1,300 km away in a former gold mine in…
