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 appli cations err controlled for other ones, is very important. In, any case. it is necessary to protect the superconductor from an excessive rise of temper ature to avoid its destruction, Our paper deals with the study of the influ ence of the thermal conductivity and the specific heat on the stability of a superconducting tube, Indeed, these parameters may have an important vari ation doe to the different materials and technology of manufacturing, Beyon d scientific curiosity, this theoretical study and the obtained results cou ld help the user to design a suitable material for a given application.
