高温超伝導体による大容量電流リードの高性能化

抄録

The use of HTS for current lead is one of the most important issues to improve the thermal performance such as minimizing the heat load and electrical power for cooling. Large currents of more than 10kA for capacity current leads are necessary for recent large-scale superconducting facilities like fusion application. We introduce several key technologies to realize such a large current capacity and high thermal performance. Theoretical and experimental results of HTS current leads show that the use of HTS introduces significant improvement on their thermal performance.
