未来环形对撞机（FCC）在其轻子构型下已被欧洲核子研究中心（CERN）选为下一代高能对撞机的主要方案。该项目旨在实现比以往高出一到两个数量级的光度。可行性研究已导致对磁铁 imperfections 的容差和校正策略的定义。这对于确保加速链主要元件之一——高能增强器（HEB）环的性能至关重要。这些策略的效率和整体性能极大地影响新的磁铁规格和容差，从而影响主要光学函数。水平和垂直轨道校正分别使用水平和垂直偏转磁铁。斜四极磁铁处理垂直色散和横向耦合。正常四极磁铁校正水平和垂直相位推进。本研究模拟了这四种校正器类型的分布，以最小化在45.6 GeV提取能量下的平衡发射度。计算了这些校正器的强度以及相关的错位。研究还讨论了所提出的校正策略的局限性和缺点。
英文摘要
The Future Circular Collider (FCC), in its leptonic configuration has been chosen by CERN as main proposition for the next high-energy collider. This project aims to achieve luminosities one to two orders of magnitude higher than ever. Feasibility studies have led to the definition of tolerances on magnet imperfections and correction strategies. This is crucial for ensuring the performance of one of the main elements of the acceleration chain, the High Energy Booster (HEB) ring. The efficiency and overall performance of these strategies greatly influence new magnet specifications and tolerances, affecting main optic functions. Horizontal and vertical orbit corrections use horizontal and vertical kickers, respectively. Skew quadrupoles address vertical dispersion and transverse coupling. Normal quadrupoles correct the horizontal and vertical phase advances. This study simulates the distribution of these four corrector types to minimize the equilibrium emittance at the extraction energy of 45.6 GeV. The calculated strengths of these correctors and the associated misalignments are presented. The study also discusses the limitations and drawbacks of the proposed correction strategy.
