DUSEL (Deep Underground Science and Engineering Laboratory) and LBNE (Long Baseline Neutrino Experiment)

The proposed Long Baseline Neutrino Experiment (LBNE) will explore the interactions and oscillations of a high-intensity neutrino beam sent from Fermi National Accelerator Laboratory (FNAL) more than 1,000 kilometers away through the earth to DUSEL at the Homestake mine. DUSEL will be one of the world's deepest underground laboratories and shield the LBNE neutrino detectors from cosmic particles at a depth of 4300 meters-water-equivalent. Two detector technologies are being considered: a 300 kTon Water Cherenkov detector deployed deep underground and a 50kT Liquid Argon Time-Projection Chamber (TPC). The physics sensitivities of the proposed experiments are summarized.
