Dilution refrigerator — Gas control system for a helium dilution refrigerator A dilution refrigerator is a cryogenic device first proposed by Heinz London. Its refrigeration process uses a mixture of two isotopes of helium: helium 3 and helium 4. When cooled below… … Wikipedia
Dry dilution refrigerator — A dry dilution system A dry (or cryogen free) dilution refrigerator is a type of dilution refrigerator that does not require the use of any external cryogens, in particular liquid helium, to operate. In the traditional design of a dilution… … Wikipedia
Helium-3 refrigerator — A helium 3 refrigerator is a simple device used in experimental physics for obtaining temperatures down to about 0.2 kelvins. By evaporative cooling of helium 4 (the more common isotope of helium), a 1 K pot liquefies a small amount of helium 3… … Wikipedia
Pulse tube refrigerator — The Pulse tube cryocooler is a developing technology that emerged largely in the early 1980 s with a series of other innovations in the broader field of Thermoacoustics. In contrast with other cryocoolers (eg Stirling cryocooler and Gifford… … Wikipedia
Magnetic refrigeration — Gadolinium alloy heats up inside the magnetic field and loses thermal energy to the environment, so it exits the field cooler than when it entered. Magnetic refrigeration is a cooling technology based on the magnetocaloric effect. This technique… … Wikipedia
Cryostat — NASA s WISE infrared instrument is kept cold by a cryostat. The cryostat can be seen at the top of the spacecraft. A cryostat (from cryo meaning cold and stat meaning stationary) is a device used to maintain cold cryogenic temperatures. Low… … Wikipedia
Pulsröhrenkühler — Ein Pulsröhrenkühler oder Pulsrohrkühler (auch Pulse Tube Kühler) ist eine auf dem Prinzip des Stirlingmotors basierende Kältemaschine. Der Vorteil gegenüber dem Stirlingmotor liegt darin, dass in der Nähe des kalten Wärmetauschpunktes keine… … Deutsch Wikipedia
