基于异常横向场效应，提出了降低高温超导带绕组磁化强度的方法。当非磁性线圈短时间用交变传输电流通电时，环形布置以及用诸如铜线的非磁性线缠绕的附加线圈的同轴布置有效地使构成承载直接传输电流的绕组的HTS带中的片电流分布均匀。采用市售涂层导体制成的层绕线圈和一对同轴排列的铜线圈，通过实验详细研究了降低绕组磁化强度对高温超导线圈中心磁场的影响。
Methods to reduce the magnetization in windings composed of high temperature superconductor (HTS) tapes are presented on the basis of the abnormal transverse-field effect. The toroidal arrangement as well as the coaxial arrangement of additional coils wound with non-magnetic wires such as copper wires is effective to uniformize the distribution of sheet current in the HTS tapes constituting the windings carrying a direct transport current when the non-magnetic coils are energized with an alternating transport current for a short time. By using a layer-wound coil fabricated with a commercially available coated conductor and a pair of copper coils with the coaxial arrangement, the influences of reducing the magnetization in the windings on the central magnetic fields of the HTS coil are studied in detail experimentally.
