Dark Matter Detector Installed Underground

Physics Professors Harry Nelson and Michael Witherell, and Physics Engineers Suzanne Kyre and Dean White are among the scientists involved in the development of the Large Underground Xenon experiment (LUX), which will be the most sensitive device yet to look for dark matter.  Thought to comprise more than 80 percent of the mass of the universe, dark matter has so far eluded direct detection. The experiment is now underwater, in a stainless steel tank, nearly a mile underground beneath the Black Hills of South Dakota.   Professor Nelson, who helped design, build, and fill the sophisticated water tank that now holds the experiment, says LUX could help solve the mystery as to the nature of dark matter. The LUX collaboration includes dozens of scientists from 17 universities and national laboratories in the U.S. and Europe.  Data collection is expected to begin in early 2013.
