Summary

It is pointed out that there could be a non-uniform current distribution in the strands of a forced-flow cooled superconductor. This affects and greatly reduces the conductor's stability margin. The authors discuss the stability degradation and quench characteristics of a forced-flow cooled superconducting coil that they have made and which has 54 strands. They have measured the stability margin of the test coil and characteristics of normal-zone propagation and pressure rise during quench using numerical-simulation code.
