Analytical studies of the thermal stability of a high temperature superconducting tube

The study of the HTS tube transition, which must be provoked for some applications or controlled for other ones, is very important. In any case, it is necessary to protect the superconductor from an excessive rise of temperature to avoid its destruction. Our paper deals with the study of the influence of the thermal conductivity and the specific heat on the stability of a superconducting tube. Indeed, these parameters may have an important variation due to the different materials and technology of manufacturing. Beyond scientific curiosity, this theoretical study and the obtained results could help the user to design a suitable material for a given application.
