โฆ Synopsis
The quench energies of uncooled superconductors are estimated based on the assumption that the specific heat and the normal state resistivity of the conductor can be approximated as power-law functions of the temperature. The results are applicable to magnets wound with high temperature superconductors.

The dynamics of the normal zone initiated by a local heat pulse in a superconductor carrying a transport current is studied theoretically. An approximate method is considered, from which analytical formulae are obtained for the minimum heat pulse energy EC required to destroy the superconductivity.
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 densi
