Last week, the U.S. Department of Energy’s Office of Science and the National Science Foundation announced support for a suite of upcoming experiments to search for dark matter that will be many times more sensitive than those currently deployed. These so-called Generation 2 Dark Matter Experiments include the LUX-Zeplin (LZ) experiment, an international collaboration formed in 2012, managed by DOE’s Lawrence Berkeley National Lab (Berkeley Lab) and to be located at the Sanford Underground Research Facility (SURF) in South Dakota. With the announcement, the DOE and NSF officially endorsed LZ and two other dark matter experiments. “The great news is we’ve been given the go-ahead,” says William Edwards, LZ project manager and engineer in Berkeley Lab Physics Division. “We’re looking forward to making what has been a proposal into a real, operational, first-rate experiment.” The LZ water shield, currently housing the LUX experiment. The LZ experiment was first proposed two years ago to search for and advance our understanding of dark matter, a mysterious substance that makes up roughly 27 percent of the universe. The experiment will build on the current dark matter experiment at SURF called the Large Underground Xenon detector, or LUX. Dark matter, so named because it doesn’t emit or absorb
