The Large Underground Xenon (LUX) detector contains 350 kg of cold liquid xenon that will scintillate when it interacts with a WIMP. The liquid xenon, held in the blue oblong vessel in this cutaway diagram, sits inside an 8-meter-diameter by 6-meter-high tank of water that reduces background signals from gamma radiation by seven orders of magnitude. Isolated from other sources of radiation by almost 1500 meters of rock, LUX will improve sensitivity to WIMPs by a factor of 100 over previous methods. (Unit: 10)
