THERMAL-CONDUCTIVITY AND CONTACT CONDUCTANCE OF BSCCO-2212 MATERIAL

Thermal conductivity of bulk high temperature superconducting material s is a very important property in the current lead applications becaus e it determines the heat load of the lead at the low temperature end. The thermal conductivity of BSCCO-2212 superconducting material has be en measured between 10 and 130 K. Our results compare favorably with o ther published results, The thermal contact conductance between a join t of BSCCO-2212 and copper has also been measured. Our results indicat e that although this kind of joint provides a relatively poor thermal interface, the electrical resistance is small. This feint is still a g ood choice for making a easy Joint which requires both thermal and ele ctrical interfacing.
