Abstract

Initial performance test results of a prototype, conductive magnetic refrigerator rejecting heat to a 4.5 K heat sink are presented. The prototype uses Gadolinium Gallium Garnet as the working material, operates in a Carnot cycle, uses NbTi magnets and employs conduction heat transfer internally. The data presented are used to validate an analytical model of the device. Performance limitations from circumferential conduction and internal friction are identified and discussed.
