在碰撞束设施中，“最终聚焦系统”必须缩小束以获得在相互作用点处所需的非常小的光斑尺寸。第一个具有局部色度校正的最终聚焦系统是为斯坦福大学直线对撞机开发的，该对撞机需要非常大的缩小倍率。同样的概念设计已经被所有未来的线性对撞机设计所采用，超导超级对撞机、斯坦福大学和KEK B工厂以及拟议中的μ子对撞机也采用了这种设计。本文综述了高能正负电子直线对撞机末级聚焦系统的总体布局、物理约束和优化技术。最后，先进的概念，以避免这些系统的局限性进行了讨论。
In colliding beam facilities, the 'final focus system' must demagnify the beams to attain the very small spot sizes required at the interaction points. The first final focus system with local chromatic correction was developed for the Stanford Linear Collider where very large demagnifications were desired. This same conceptual design has been adopted by all the future linear collider designs as well as the SuperConducting Supercollider, the Stanford and KEK B-Factories, and the proposed Muon Collider. In this paper, the over-all layout, physics constraints, and optimization techniques relevant to the design of final focus systems for high-energy electron-positron linear colliders are reviewed. Finally, advanced concepts to avoid some of the limitations of these systems are discussed.
