Summary

In order to achieve the designed performance of a superconducting magnet, one of the key points to be considered carefully is the stability of the magnet. For a large superconducting magnet with huge stored energy, one always demands that the magnet is thermally stabilized. Since nobody really knows the limit of the size of the disturbance in a large magnet, and since a large magnet is economically permitted to operate at a relatively low current density, the MHD magnet to be built for the Coal-Fired Flow Facility (CFFF) at the University of Tennessee Space Institute is designed to adhere to the absolute stability criterion. Although for the compactness reason, because of the air shipment, the US SCMS (U-25) superconducting dipole magnet was designed to have higher current density and can recover following a generation of a local normal zone. To test the stability characteristics of these two magnet systems, the US SCMS conductor and the CFFF Grade A conductor were used to construct various samples. Two of these samples were short sample type set ups. They were easy to make and could furnish quick and rather reliable information. But, to eliminate the end effect and to look deeply into the stability of the conductor, two test samples with fairly long conductors also were made. The experimental setup and test results are discussed. (TFD)
