中国科学院等离子体物理研究所（ASIPP）研制了由14T低温超导（LTS）背景场磁体和11T YBCO插入线圈组合而成的25T全超导磁体。采用无绝缘缠绕技术的原型插入线圈的内径和外径分别为16 mm和54 mm，由10个单饼缠绕约220 m的YBCO导体组成，有限公司（SSTC）。在77K和4.2K下进行了初步试验。测试结果表明，线圈在制造和浸渍过程中性能没有下降，在14.3 T的背景场和10.6 T的自场下，线圈均能产生9.7 T的稳态中心磁场。本文将全面介绍YBCO插入线圈的详细设计、结构和初步试验结果。
The 25 T all superconducting magnet designed as a combination of 14 T low temperature superconductor (LTS) background field magnet and a 11 T YBCO insert coil has been developed at Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). The prototype insert coil with no-insulation winding technique has the inner and outer diameters of 16 mm and 54 mm, respectively, and consists of ten single pancakes wound with about 220 m of YBCO conductors produced by Shanghai Superconducting Technologies Co., Ltd (SSTC). The preliminary tests were carried out at 77 K and 4.2 K. The test results show that the performance of coil did not degrade during the manufacturing and impregnation process, and it can generate a steady-state central magnetic field of 9.7 T in the 14.3 T background field, and 10.6 T in self-field. The detailed design, construction, and preliminary test results of the YBCO insert coil will be fully introduced in this paper.
