Quantification of disturbance energy due to conductor motion and stability analysis of superconducting composite wire

The authors propose a model to quantify the disturbance energy due to conductor motion. The model relates the disturbance energy to mechanical properties of the conductor, electromagnetic force, and winding structure. The stability of a superconducting composite conductor subject to an abrupt conductor motion is analyzed on the basis of the proposed model. It is pointed out that the stability of the conductor is improved by decreasing the distance between spacers placed between the conductors. However, it is pointed out that there is a limit to the improvement, because of limited accuracies of the conductor and spacer dimensions.<
