Close to Launch of the Most Sensitive Dark Matter Detector Ever

On Feb. 10 LUX, the Large Underground Xenon experiment at the Sanford Underground Research Facility in South Dakota, topped off its cylindrical titanium tank with 350 kilograms of liquid xenon, condensed from circulating xenon gas in the precooled tank. LUX now awaits several weeks of xenon purification before beginning data collection as the most sensitive search for dark-matter WIMPs (weakly interacting massive particles) ever undertaken. The Physics Division’s Gil Gilchriese and Bob Jacobsen are members of LUX, and Kevin Lesko of the Nuclear Science Division leads the Sanford Lab Operations office. More>
