| Popis: | The method consists in the monitoring of the temperature variation of a superconductor tape subjected to a trapezoidal current pulse. Simulations of the experiment were performed using the lumped capacitance model and also the two dimensional finite element method. Both were successful in reproducing the sample's reactions to the heat pulse. This increases our understanding of the propagation of internally generated heat in superconductors and will facilitate, for example, the study of AC losses in these materials. The thermal conductivity deduced from the measurements are consistent with the literature. |
