Transient Response of a Composite Superconducting Wire in Spatially Periodical Longitudinal A.C. Magnetic Fields
In this paper analytical results are presented concerning the transient response of a composite superconducting wire in spatially periodical longitudinal ac magnetic fields. Locally solutions are positively, negatively or unsaturated in a region and the positions of the interfaces between different regions are calculated. One dominant time constant has to be included in the analysis due to the twist. Other time constants can be neglected, because the periodicity length of the field is assumed to be much larger than the radius of the wire. We focus on the influence of the dominant time constant on the interfaces.
