A rapid, semiempirical method of calculating the stability margins of superconductors cooled with subcooled He-II

A rapid, semiempirical method is presented for calculating the stability margins of superconductors cooled with subcooled He-II. Based on a model of Seyfert et al., the method takes into account both time-dependent Gorter-Mellink heat transport and the effects of interfacial Kapitza resistance. The method has been compared favorably with heat transfer data of Seyfert et al., stability data of Meuris, and stability data of Pfotenhauer and van Sciver.
