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 the conductor, inter-sub-cable coupling losses in it are decreased. As a result, not only the total coupling loss in the conductor is decreased, but also high stability is maintained due to the low contact resistance between the sub-cables. The fundamental performance of the conductors designed using our method has been confirmed by measuring the coupling 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 with sub-cables. The results obtained successfully show the validity of our new design method.
