High-field Nb 3 Sn dipoles generating more than 15 T are strongly required, whether it is for the future circular collider studies (CERN 16 T Development Program, CEA-CERN demonstrator) or for test stations (FRESCA2, HEPDipo). The use of magnets graded with different cables now becomes unavoidable to allow for more compact and cost-effective designs. This article presents a 2-D parametric study, which explores possible options for an optimal grading. The study uses analytical formulas for current sources to allow for fast and accurate parametric studies. Block coils are considered, using different cable sizes, and therefore, different current densities. Various parameters are also explored, such as cable combinations, current density ratios, conductor performance, and position of the blocks. The article shows in particular what are the optimal grading factors and amount of conductor required to reach a given bore field, considering margins on the load line, and limitations in current density for quench protection.

分级在 Nb3Sn 高场块线圈偶极子中的应用



无论是未来的圆形对撞机研究(CERN 16 T 开发计划、CEA-CERN 演示器)还是测试站(FRESCA2、HEPDipo),都强烈需要产生超过 15 T 的高场 Nb 3 Sn 偶极子。现在,为了实现更紧凑和更具成本效益的设计,使用不同电缆分级的磁铁变得不可避免。本文介绍了一项二维参数研究,探讨了最佳分级的可能选择。该研究使用电流源的分析公式来进行快速、准确的参数研究。考虑使用不同电缆尺寸的块线圈,因此使用不同的电流密度。还探讨了各种参数,例如电缆组合、电流密度比、导体性能和块的位置。该文章特别展示了达到给定孔场所需的最佳分级系数和导体数量,考虑负载线的裕度以及失超保护的电流密度限制。
