Abstract :
We measured operating temperature dependence or normal zone propagation velocity in longitudinal direction and thermal property with regard to Ag sheathed Bi-2223 superconducting single core and multifilamentary tapes. Each experiment, with the test sample cooled by a cryocooler, covers the operating temperature range 10~40 K and It/Ic range 0.4~0.9 (where It is the transport current and Ic is the critical current in each operating temperature, Top). And, we also carried out numerical analysis by a three-dimensional finite element method in order to make clear the mechanism of normal zone propagation in high-temperature superconducting (HTS) conductors
