Abstract :
High-Tc superconductor has been expected as a current lead between a low Tc superconductor and a power supply for a large-scale superconducting magnet system because of its advantages of a heat load to a cryogenic system and a high transfer current density. Bi-2212 bulk superconductor is a candidate material for this kind of current lead. To design a current lead using high-Tc superconductor, we investigated mechanical properties of a Bi-2212 bulk which was prepared by a diffusion process. A concept design of a current lead reinforced by using a glass-epoxy was considered.
