    Pulse tube coolers are commonly used cryocoolers in dry dilution refrigerators. Dry dilution refrigerators generally follow one of two designs. One design incorporates an inner vacuum can, which is used to initially precool the machine from room temperature down to the base temperature of the pulse tube cooler (using heat-exchange gas).

    en.wikipedia.org/wiki/Pulse_tube_refrigerator

    In most coolers gas is compressed and expanded periodically. Well-known coolers such as the Stirling engine coolers and the popular Gifford-McMahon coolers have a displacer that ensures that the cooling (due to expansion) takes place in a different region of the machine than the heating (due to compression). Due to its clever design, the PTR ...

    Fig.1 Schematic diagram of a Stirling cooler. The system has one piston at ambient temperature T a and one piston at low temperature T L. The basic type of Stirling-type cooler is depicted in Fig.1. It consists of (from left to right): a piston; a compression space and heat exchanger (all at ambient temperature T a) a regenerator; a heat exchanger
