SURF - Sept. 2012 presentation Friday, January 18, 2013 3:57 PM Sanfo1

Current Science Program • LUX - Large Underground Xenon Experiment (Dark Matter Search) - Direct search for WIMPs using 350 kg xenon within ultra-pure titanium cryosta - Surface Laboratory checkout activities to exercise procedures, test installation and detector operations just wrapping up for transition to Davis Campus MJD - MAJORANA DEMONSTRATOR (Neutrinoless Double Beta Decay) - Investigate neutrinoless double beta decay using 40 kg Ge in two cryostats (start with natural Ge, add up to 30 kg enriched 76 Ge) - Electroforming copper for detector shielding on 4850L - Will deploy detector in Davis Campus; Experiment is a pathfinder for 1-tonne scale • Biology, Geology, Engineering (BGE) experiments operational at SURF - Program of characterization (including physics): Biology sampling, seismic/ frequency, microclimate, physics backgrounds - Includes Center for Ultralow Background Experiments in the Dakotas (CUBED (EPSCoR/SD) experiment planned for installation in the Davis Campus

Extending the life of the lab We have current proposals in to the NSF & DOE; • DIANA (Nuclear astrophysics) would run 2015 through 2022 +. • LZ (2 nd generation Dark Matter) would run from 2015 through 2022. • Low Background Counting Facility would run throughout all experiments. • LBNE (Long Baseline Neutrino Experiment) would run from 2016 through 2040 • Reengaging the NSF for Geology, Biology and other experiments ..
