Abstract

Quench characteristics of low temperature superconductor (LTS) and high temperature superconductor (HTS) hybrid superconductor made of NbTi/Cu wire and Bi2223/Ag tape are investigated experimentally. The results indicate: the minimum quench energy (MQE) of the hybrid conductor is much larger than NbTi/Cu; quench propagation velocity (QPV) and quench recovery time (QRT) are both less than NbTi/Cu. Those properties make the stability of the hybrid conductor better than NbTi/Cu, quench detection easier than Bi2223/Ag and operating current density greater than pure metal-stabilized superconductor. With advantages of high engineering current density and improvement of stability, the hybrid superconductor is expected to have some potential applications in large scale magnet and conductor-cooled magnets particularly.
