Abstract

A new concept of LTS/HTS hybrid conductor was recently proposed. However, little theoretical and experimental research has been done in aspects of its stability. Based on the electromagnetic model of the hybrid conductors, current redistribution between LTS and HTS is numerically investigated in transient process. Furthermore, temperature distribution, quench velocity and minimum quench energy are also simulated by solving thermal-magnetic coupling equivalent equations. Comparing with conventional superconducting conductor, the simulated results show that the stability of the hybrid conductor can be greatly improved and it has potential application in large scale and conduction cooled superconducting magnet.
