为了在我们的 HOMER II 设施中使用超导 LTS-HTS 混合磁体获得 25 T 的磁场，我们构建并测试了第一个 5 T 高温超导 (HTS) 插入线圈原型。 HTS 插入物由 16 个双层煎饼组成，由美国超导公司制造的不锈钢增强 Bi-2223 胶带制成。 HTS 线圈在 1.8 K 下运行，在 151.2 A 电流下产生 5.4 T。在我们的 HOMER I 设施提供的 11.5 T 背景场中，多次获得 16.9 T 的总场。测试期间没有观察到线圈的训练或失超，但在预热后，检测到一个双层煎饼的缠绕缺陷，可能是由于胶带膨胀所致。介绍并讨论了线圈的设计和测试结果。
With the goal of obtaining a magnetic field of 25 T in our facility HOMER II with a superconducting LTS-HTS hybrid magnet, a first prototype 5 T high temperature superconducting (HTS) insert coil has been constructed and tested. The HTS insert consists of 16 double pancakes made of stainless steel reinforced Bi-2223 tapes manufactured by American Superconductor. The HTS coil was operated at 1.8 K and produced 5.4 T at a current of 151.2 A. In a background field of 11.5 T provided by our facility HOMER I, a total field of 16.9 T was obtained several times. No training or quench of the coil was observed during the test, but after warming up a defect in the winding of one double pancake was detected, presumably due to a ballooning of the tape. The design of the coil and the results of the test are presented and discussed.
