Water tank

Water tank

The Large Underground Xenon (LUX) dark matter detector is seen here after it was installed at the center of a water tank that will be filled with more than 70,000 gallons of ultra-pure deionized water. The water will shield the detector from background radiation. The tank is lined with highly reflective white Tyvek sheets. Four strings of photomultiplier tubes (PMTs) will detect faint trails of light—a signal that high-energy particles caused by cosmic radiation have penetrated the earth to the 4850 Level. That light will help researchers rule out false signals. Photo credit: Matthew Kapust.
