Increased normal zone propagation velocity in superconducting segments
There is described herein a superconducting segment and method of making same comprising one or several layers with very high electrical resistivity, acting as a current flow diverter when the current transfers from the superconductor to the stabilizer. The purpose of this current flow diverter is: i) to increase the contact resistance between the superconductor and the stabilizer, by reducing the contact area, and ii) to force the current to flow along a specific path, so as to increase momentarily the current density in a specific portion of the stabilizer. The consequence of i) and ii) is that heat generated at the extremities of the normal zone is increased and spread over a longer length along the superconducting segment, which increases the NZPV and thus, the uniformity of the quench.
