Nuclear Demagnetization Systems are used to cool samples to ultra-low temperatures (below 4mK).
Cryomagnetics’ Nuclear Demagnetization Magnets incorporate a main high field coil with series wound cancellation coils. Cancellation coils are employed to minimize heating effects from magnetic flux on low temperature inserts. The location and strength of the cancellation coils are unique to each configuration and are specified by the customer. These magnets are also commonly used with dilution refrigerators (< 10mK).
Cryomagnetics has manufactured NbTi Nuclear Demagnetization Magnets up to 9T (4.2K), 11T (2.2K). Nb3Sn based versions delivered include up to 17T (4.2K), 19T (2.2K).
