LUX Components

Caption: The LUX detector (left) is filled with liquid xenon cooled to minus 108 degrees Celsius. Arrays of photomultiplier tubes (lower right) are at top and bottom and catch the faint light when a WIMP interacts with a xenon nucleus. Electrons knocked loose in the collision are pulled by a strong electric field into the xenon gas near the top of the tank and emit a brighter flash; By comparing the flashes and the time between them, the energy, position, and nature of the collision are determined. The xenon container is immersed in a tank of water to provide extra shielding (upper right).
