PREDICTION OF SUPERCONDUCTOR BEHAVIOR WHEN SUBJECTED TO A LOCAL THERMAL DISTURBANCE

The stability of a one-dimensional composite superconductor subjected to a thermal disturbance is studied by considering, in addition to the amount of disturbance energy, the effect of the disturbance temperatu re profile. An analysis is conducted for the stationary thermal condit ion, and the result is compared with the transient solution in terms o f characteristic functionals. It is shown that a map involving two cha racteristic functionals can precisely characterize the recovery-quench ing behaviour of the superconductor.
