Abstract :
Aluminum-stabilized NbTi superconducting wires have been developed for the purpose of increasing the stability margin of a close-packed superconducting coil with high current density. The effects of high purity aluminum stabilizer on the stability margin and the normal propagation velocity were investigated in the coil operation. It was verified that the coil stability margin is significantly improved by using the aluminum-stabilized superconducting wire. The experimental data of the coil stability margin are in good agreement with the calculated results by one-dimensional transient computer simulation analysis
