Sentences with phrase «as liquid xenon»

Many of them rely on high - purity materials such as liquid xenon and germanium crystals, cooled to low temperatures and placed in deep mines to shield the devices from the continuous spray of ordinary particles that strike Earth's atmosphere.

Not exact matches

Experiments like SuperCDMS and LUX - ZEPLIN rely on metal germanium crystals and liquid xenon, respectively, as their dark matter finders.

An international team of physicists is preparing XENON100, a simple experiment with a huge ambition: to record the moment when a bit of dark matter — known as a weakly interacting massive particle, or WIMP — smacks into the nucleus of an atom of liquid xenon, triggering a flash of light and an electric charge.

To shield the detector as much as possible from natural radioactivity in the cavern, the detector (a so - called Liquid Xenon Time Projection Chamber) sits within a cryostat submersed in a tank of water.

Also, as a single nearly spherical liquid target, the xenon system has a much smaller surface - to - volume ratio than multiple germanium detectors and therefore is less susceptible to noise.

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.
