The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW. Some can have input powers as low as 2–3 W. Large systems, such as those used for cooling the superconducting magnets in particle accelerators are more often called cryogenic refrigerators. Their input powers can be as high as 1 MW. In most cases …
WebThe machine’s internal cryocooler has been designed to lift 50W of heat from a 50K cold tip and reject to a 300K ambient environment. This cryocooler is also intended to be light weight (<10kg), small diameter (<100mm), and capable of withstanding 6800RPM rotation about its central axis such that it can be integrated into the shaft of the HEMM.
