摘　　要：中国科学院高能物理研究所超导磁体团队为大型强子对撞机亮度升级项目(HL-LHC)研制了一种斜螺线管型超导二极磁体,为评估CLIQ失超保护系统在该磁体上的性能表现,建立CLIQ失超保护系统在CCT超导磁体上的数值模拟分析方法,根据计算结果搭建了一套CLIQ失超保护系统进行实验验证。数值模拟结果与实验结果证明了CLIQ失超保护系统对CCT超导磁体的高效保护,同时两者十分吻合。Instituteof High Energy Physics is developing Canted-Cosine-Theta(CCT)superconducting dipole magnets for HL-LHC project.To evaluate the performance of the Coupling Loss Induced Quench(CLIQ)system on this magnet,a numeri⁃cal simulation and analysis method for the CLIQ system on CCT magnets was established,and a set of CLIQ system was built for experimental verification based on the calculation results.The numerical simulation results and the experimental results demon⁃strate the efficient protection of the CLIQ system on CCT superconducting magnets,and both are in good agreement.
