compact Stranded Sperconducting Conductors with both Low AC Loss and High Stability II.Experiment to Confirm Fundamental Performance

摘要

In our previous paper,we proposed a new method for designing compact stranded superconducting conductors as a solution to the dilemma that low loss and high stability could not be simultaneously attained in commonly used conductors.By adjusting the twist pitches and directions of the sub-cables in teh conductor,inter-sub-cable coupling losses in it are decreased.As a result,not only the total coupling loss in th conductor is decreased,but also high stability is maintained dur to the low contact resistance between the sub-cables.The fundamental performance of the conductors designed using our method has been confirmed by measuring th ecoupling loss and the minimum quench energies in the conductor.Our measurements are,in this case,carried out using Rutherford cables with strands instead of the conductors iwth sub-cables.The results obtained successfully show the validity of our new design method.
