Abstract

The impact of high temperature ceramic superconductors on the thermal stability of superconducting devices is two-fold. Firstly, nitrogen becomes the probable cryogenic coolant, and secondly, the new materials exhibit thermophysical properties different from conventional superconductors. This work analyses transient heat transfer to subcooled and supercritical nitrogen and compares the results to those for helium. An extensive review of the thermophysical properties of YBa2Cu3O7 assesses their effect on thermal stability. Anisotropic thermal conductivity is shown to strongly influence the intrinsic thermal stability of a composite strip superconductor.
