高能物理研究所（IHEP，北京，中国）正在提出一个两级粒子对撞机：CEPC-SppC。第一阶段是一个圆形电子-正电子对撞机（CEPC），预计将对希格斯玻色子进行高精度研究。CEPC实验完成后，将升级为超级质子-质子对撞机（SppC），旨在发现标准模型之外的物理。CEPC和SppC的加速器周长为50 ~ 70 km。SppC所需的偶极保持强度为20 T。作为IHEP高保持加速器磁体技术长期研发计划的开始，计划在未来五年内开发15 T短样品保持Nb 3Sn偶极子。采用共线圈结构，为两个最大直径为60 mm的孔提供空间。在15 mm的参考半径下，可达到10-4级的保持均匀性。对这种高保持共线圈偶极子进行了磁分析建模和有限元截面研究，并将在这里介绍。还将介绍20 T共线圈偶极子的初步横截面研究;该设计基于Nb 3Sn和HTS超导体的当前Jc水平。
The Institute of High Energy Physics (IHEP, Beijing, China) is proposing a two-stage particle collider: CEPC-SppC. The first stage is a circular electron-positron collider (CEPC), expected to carry out high-precision studies on Higgs bosons. Upon completion of the CEPC experiment, it will be upgraded to a super proton-proton collider (SppC), aiming at the discovery of physics beyond the standard model. The circumference of the accelerator for CEPC and SppC will be 50 ~ 70 km. The required dipole held strength is 20 T for SppC. As the start of a long-term R&D plan for high-held accelerator magnet technology at IHEP, a 15-T short sample held Nb3Sn dipole is planned to be developed within the next five years. The common-coil configuration is adopted to provide space for two apertures with a maximum diameter of 60 mm. The 10-4 level held uniformity will be reached at a reference radius of 15 mm. Magnetic analytical modeling and FEM cross section study of this high-held common-coil dipole has been done and will be presented here. A preliminary cross section study of the 20-T common-coil dipole will also be introduced; the design is based on the current Jc level of Nb3Sn and HTS superconductors.
