Cut-away view of the Daikin cryopump. This device is used to produce ultra-low temperatures. It operates on the principle that gasses cool when expanded,and may produce temperatures of as low as 4 Kelvin (-269 Celsius). This is sufficiently cold to liquefy helium. Ultra-low temperatures of this order are useful in some areas of physics,particularly in superconductor research | |
