Status and Progress at the Sanford Lab at Homestake

In July 2007 the Homestake gold mine in the Black Hills of South Dakota was selected by the NSF as the site for DUSEL (the Deep Underground Science and Engineering Laboratory). The SDSTA (South Dakota Science and Technology Authority), landlord of the mine property and charged by the State to re-open the mine, has undertaken the process of refurbishing shafts, re-establishing water-pumping infrastructure and deploying of an “early science” program, all in preparation for the formal commencement of DUSEL construction anticipated in FY2013. Excellent progress is being made on all these fronts and will be reported. The water level is dropping steadily as we pump and treat approximately 2 million gallons of water per day; we expect to have the 4850 level dry in a few months. Early science includes LUX (liquid-xenon dark-matter search), elements of the Majorana (0nbb) experiment, and deployment of several seismometer stations. A first micro-biology paper has just been published!
