Abstract :
The current distribution characteristics of low temperature superconductor (LTS) and high temperature superconductor (HTS) hybrid superconductor, made of NbTi/Cu wire and Bi2223/Ag tape, were studied numerically and experimentally. Results indicate: with the increase of temperature the current transfers from LTS to HTS, and compared to NbTi/Cu wire, NbTi/Bi2223 hybrid superconductor has higher operating current and better stability. This kind of hybrid superconductor is expected to have potential application in high field magnet and conduction-cooled magnet particularly.
