In order to establish new design methods of low-AC-loss superconducting coils cooled by cryocooler with high efficiency, we proposed a new low-AC-loss structure for Bi-system (Bi-2223) oxide-superconducting multifilamentary taped wires on the first stage, which are promising practical wires developed. We showed a new design method of transport AC losses generated in superconducting coils with magnetic field distribution and local AC loss properties of superconducting windings on the second stage. We also proposed advanced structures for superconducting coils with highly uniform distribution of magnetic field by means of reducing magnetic hysteresis remarkably in taped windings

为了建立新型高效制冷机冷却低交流损耗超导线圈的设计方法，我们在第一阶段提出了一种新型的低交流损耗Bi系（Bi-2223）氧化物超导多芯带材结构，这是一种很有发展前景的实用化带材。提出了一种新的设计方法，该方法利用第二级超导线圈的磁场分布和局部交流损耗特性来计算超导线圈中的交流损耗。提出了通过显著降低带绕组磁滞来实现磁场高度均匀分布的超导线圈的先进结构
