A 10 K magnet for space-flight ADRs Original Research Article

Future NASA missions will include detectors cooled by adiabatic demagnetization refrigerators (ADRs) coupled with mechanical cryocoolers. A lightweight, low-current 10 K magnet would allow the interface between these devices to be at temperatures as high as 10 K, adding flexibility to the instrument design. We report on the testing of a standard-technology Nb3Sn magnet and the development of a lightweight, low-current 10 K magnet. We also discuss the outlook for flying a 10 K magnet as part of an ADR system.
