✦ Synopsis

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 twodimensional heat diffusion analysis: one concerning intrinsic stability, the other concerning recovery. The results agree with previous stability behaviour data of low Tc Nb-Ti and high Tc YBa2Cu307 superconductors.
