THE EFFICIENT USE OF STABILIZING MATERIALS IN SUPERCONDUCTING SOLENOIDS.
Abstract
The problem of stability of superconducting solenoids is considered from a thermal point of view. The transient heat conduction equation for a superconducting tape clad with normal material and operated in a current sharing mode is studied. The composite conductor is considered stable if its final temperature in the current sharing mode corresponds to the critical temperature for the initial current density in the superconductor. Using this criterion, the operating point of the superconductor and its stabilizing cladding thickness can be chosen to give a maximum average current density in the composite at any field. Calculations are given for Nb3Sn tape clad with OFHC copper and with high purity aluminum. (Author)
