Summary

The stability of a tape/film superconductor of a large aspect ratio is studied by considering the transverse normal zone behaviour subjected to an instantaneous thermal disturbance. Different types of behaviour in terms of stable superconducting operation, current sharing, quenching and superconductivity recovery have been identified. A stability criterion was developed based on heat conduction analyses for the current sharing steady state and the quenching steady state. The criterion was validated by the transient stability behaviour results for a niobium-titanium superconductor obtained through the finite difference method. The effects of operating current density and the composite superconductor's dimensions on the stability performance were also investigated.
