Discussion of Thermal Equilibrium Current of the Superconductor

Abstract

If there is a local thermal insulation on the superconductor surface, the thermal equilibrium transport current can be measured. A simple graphical scheme is presented incorporating heat transfer and heat generation characteristics into the calculation of the stability of superconductors with local thermal insulation, modifying the equal area method presented by Maddock, et al. Minimum thermal equilibrium transport currents were calculated and compared with the experimental results.
