Abstract

Thermal conductivity of bulk high temperature superconducting materials is a very important property in the current lead applications because it determines the heat load of the lead at the low temperature end. The thermal conductivity of BSCCO-2212 superconducting material has been measured between 10 and 130 K. Our results compare favorably with other published results. The thermal contact conductance between a joint of BSCCO-2212 and copper has also been measured. Our results indicate that although this kind of joint provides a relatively poor thermal interface, the electrical resistance is small. This joint is still a good choice for making a easy joint which requires both thermal and electrical interfacing.<>
