초록

This paper describes on concerning electromagnetical and thermal behaviors during normal transition in Bi-2223/Ag superconducting multifilamentary tapes by conduction cooling. Some experiments were carried with operating temperature, 10-40K, and transport current as parameters in zero magnetic field. Sample tapes are transited normally with heater to intiate a quench. The voltage and temperature properties which accord to normal transition are measured by voltage taps and thermocouples attached to sample tapes, we also calculated longitudinal and transverse directions normal-zone propagation velocities from the voltage traces.
