Helium-3 refrigerator

A helium-3 refrigerator is a simple device for obtaining temperatures down to about 0.2 kelvins. A 1-K pot is used to liquefy a small amount of helium-3 in a small vessel called a helium-3 pot. Evaporative cooling of the liquid helium-3 (which due to its high price is usually contained in a closed system to avoid losses) cools the helium-3 pot to a fraction of a degree kelvin.
