Abstract
Argonne National Laboratory is building a large superconducting dipole magnet[1] for MHD research at the University of Tennessee Space Institute-Coal Fired Flow Facility (UTSI-CFFF). In designing such a large (170-MJ stored energy) magnet, great attention must be devoted to the safety of the magnet and personnel. The conductor for the UTSI-CFFF magnet incorporates significant copper stabilizer, which both insures its cryostability [2] and contributes to the magnet safety. This paper first presents the quench analysis, followed by the cryostat fault condition analysis. Two analyses of exposed turns follow: The first shows that gas cooling protects uncovered turns, and the second that the cryostat pressure relief system protects them. Finally the failure mode and safety analysis is presented.
