本文介绍了一种持久模式高温超导（HTS）匀场线圈的设计、制造和测试结果。从美国超导公司（AMSC）生产的46毫米宽的Y - Ba - Cu - O带材上切割出一个Z1矩形环原型匀场线圈，并在77 K下进行了测试。高温超导匀场线圈比传统的铌钛（NbTi）匀场线圈薄得多，它被放置在主磁体内部，不受其抗磁壁效应的影响。结合其>12 T和>10 K的运行能力，高温超导匀场线圈为核磁共振（NMR）磁体（包括无液氦和常规的磁体）提供了一种通用的设计选择，并且在下一代核磁共振磁体中极具吸引力。（C）2013美国物理联合会出版有限责任公司。
Design, fabrication, and test results of a type persistent-mode high-temperature superconductor (HTS) shim coil are presented. A prototype Z1 rectangle-loop shim, cut from 46-mm wide Y-Ba-Cu-O tape manufactured by AMSC, was fabricated and tested at 77 K. The HTS shim, much thinner than the conventional NbTi shim, is placed inside the main magnet and immune to its diamagnetic wall effects. Combined with the >12-T and >10-K operation capability, the HTS shim offers a versatile design option for nuclear magnetic resonance (NMR) magnets, liquid-helium-free as well as conventional, and is particularly attractive in the next generation NMR magnets.
