The first null result this summer came from the Large Underground Xenon (LUX) experiment, a third of a metric
ton of liquid xenon held at a frosty − 100 degrees Celsius inside a giant, water - filled tank buried one and a half kilometers under the Black Hills of South Dakota.
One of the latest null results in the search for WIMPs came from the Large Underground Xenon (LUX) experiment, a third of a ton
of liquid xenon held at a frosty — 100 degrees Celsius inside a giant water - filled tank buried one and a half kilometers beneath the Black Hills of South Dakota.
Takeuchi has spurred efforts to construct another detector in the Kamioka mine, known as XMASS, that uses a one - ton
tank of liquid xenon cooled to -100 °C to observe collisions between WIMPs and the frigid noble gas.
Xenon100, a
tub of liquid xenon in Gran Sasso, and CDMS II, next door to CoGeNT, have so far come up empty.
The way we go about this search is to wait for a particle of dark matter to come into contact with our device, which is basically a
pot of liquid xenon [an element that is used, in gas form, in the very bright headlights of many new cars] sandwiched between two detectors.
Inside the massive device, which contains a third of a ton
of liquid xenon inside a titanium vessel, an array of sensitive light detectors wait for the moment when a dark matter particle will collide with a xenon atom and emit a tiny flash of light.
Xenon100 is designed to search for the most favored dark matter particle candidate — the weakly interacting massive particle (WIMP)-- by watching for signs that a WIMP has recoiled off an atom in a
tank of liquid xenon.
Finally, inside the suspended flask — at the very center of this series of Matryoshka dolls — sits one - third of a ton
of liquid xenon, supercooled to below -169 F and carefully monitored by sensitive detectors.
