David Montanari (Fermilab) - The LBNE Cryostat and Cryogenic Systems

Description
Abstract: The Long-Baseline Neutrino Experiment (LBNE) is a broad scientific program being developed in the United States as an international partnership. LBNE consists of an intense neutrino beam produced at Fermi National Accelerator Laboratory (Fermilab), a highly capable set of neutrino detectors on the Fermilab campus (Near Detector), and a large underground liquid argon Far Detector at Sanford Underground Research Facility (SURF) in the state of South Dakota. LBNE will make detailed studies of neutrino oscillations including measurements of the mass hierarchy and CP violation that take advantage of the 1300 km baseline. At the far site, the large underground detector will open a new window to the search for nucleon decay, supernova neutrinos, and interesting astrophysical phenomena. This talk will describe the plans for the LBNE Far Detector Cryostat and Cryogenic Systems and their current status. The LBNE 35 ton prototype will also be presented: it is the LBNE prototype that we have built at Fermilab to test the purity in a membrane cryostat and the deployment of TPCs. Long term plans and current status will be detailed.
