Abstract

The quenching and recovery behaviour of a tape/film type superconductor subjected to an instantaneous thermal disturbance is investigated. A criterion is developed regarding the possibility of superconductivity recovery after quenching. The criterion involves comparison of two critical current density ratios determined by a two-dimensional heat diffusion analysis: one concerning intrinsic stability, the other concerning recovery. The results agree with previous stability behaviour data of low T-c Nb-Ti and high T-c YBa2Cu3O7 superconductors.
