Summary

It is expected that the normal-zone propagation of a high-temperature superconductor is slower than that of a low-temperature superconductor because of its large heat capacity. If the normal-zone propagates too slowly, hot spots will develop, possibly resulting in permanent conductor damage. Accordingly, there is a need to measure propagation quantitatively for designing high-temperature superconductor magnets. The paper describes the electromagnetic and thermal behavior of bismuth-2223/silver superconducting multifilament tapes during normal transition by conduction cooling. Some experiments were carried out under the conditions of operating temperature at 10-40 K and transport current as parameters in a zero magnetic field.
