最近，高温超导（HTS）带的特性已经得到提前，并且HTS磁体已经被构造和演示。然而，与低温超导（LTS）线材相比，高温超导带材具有不同的热特性。此外，Bi2223/Ag带和YBCO涂层导体对于外部磁场程度的依赖性具有不同的特性。因此，有必要在磁体设计阶段考虑高温超导带材的这些特性。我们提出了一种使用 Bi2223/Ag 带的超导线圈的优化设计方法。并利用优化算法之一的模拟退火(SA)在B-I特性、存储能量等诸多约束下对所提出的配置进行优化。显示了优化方法的详细信息及其在使用 YBCO 涂层导体的 SMES 线圈 (72 MJ) 上的应用示例。
Recently, the properties of high temperature superconducting (HTS) tapes have been in advance and HTS magnets have been constructed and demonstrated. However, the HTS tapes have thermal different characteristics compared with the low temperature superconducting (LTS) wires. Moreover, Bi2223/Ag tapes and YBCO coated conductors have the different properties about the dependence on the degree of external magnetic field. Therefore it is necessary to consider these characteristics of HTS tapes at magnet design stage. We proposed an optimal design method for superconducting coils using Bi2223/Ag tapes. And the proposed configuration is optimized by using the simulated annealing (SA), which is one of the optimization algorithms, under a lot of constraints such as B-I characteristic, storage energy, and so on. The details of the optimization method and an example of its application to SMES coils (72 MJ) using YBCO coated conductors are shown.
