Abstract
We present a ) winding technique for an HTS (high temperature superconductor) magnet consisting of double-pancake (DP) coils. The NI enables an HTS magnet self-protecting and the MW minimizes the detrimental anisotropy in current-carrying capacity of HTS tape by assigning tapes of multiple widths to DP coils within a stack, widest tape to the top and bottom sections and the narrowest in the midplane section. This paper presents fabrication and test results of an NI-MW HTS magnet and demonstrates the unique features of the NI-MW technique: self-protecting and enhanced field performance, unattainable with the conventional technique.
摘要
我们提出了一种用于由双饼式（DP）线圈组成的高温超导（HTS）磁体的绕组技术。非理想电感（NI）使高温超导磁体具有自我保护功能，而多宽度绕组（MW）通过为堆叠中的双饼式线圈分配多种宽度的带材，将最宽的带材用于顶部和底部部分，最窄的带材用于中间平面部分，从而使高温超导带材载流能力中的有害各向异性最小化。本文介绍了一个非理想电感 - 多宽度绕组高温超导磁体的制造和测试结果，并展示了非理想电感 - 多宽度绕组技术的独特特性：自我保护和增强的磁场性能，这是传统技术无法实现的。
