โœฆ Synopsis


The transient equation was solved in the vicinity of the boundary between quenching and recovery in full detail for a heat input introduced as the disturbance, which takes a space-wise and time-wise rectangular shape, and the true boundaries in the safety maps are shown. Though the dynamic analysis is indispensable to confirm the safety of the superconductor, the space-wise and time-wise shape of the distribution of the disturbance should be taken into account in the analysis to locate the real boundary between quenching and recovery of superconductors. The MPZ scrutiny of safety only by the stored energy in excess of the bath temperature at static equilibrium works in the limited region of relevant paremeters.
