我们目前的研究，旨在确定第一个概念性的解决方案的准直系统的强子-强子的未来圆形对撞机（FCC-hh）的选择。基线准直布局是基于当前LHC准直系统与FCC-hh能量的比例。它目前包括一个专用的电子感应加速器清洁插入以及准直器在实验插入，以保护内部的三胞胎。定义了FCC-hh的孔径模型，并在考虑机械和光学缺陷的情况下计算了最高能量下的几何验收。根据这些研究，定义了保护机器所需的准直器设置。准直系统的性能，然后评估粒子跟踪模拟工具，假设一个完美的机器。
We present studies aimed at defining a first conceptual solution for a collimation system for the hadron-hadron option for the Future Circular Collider (FCC-hh). The baseline collimation layout is based on the scaling of the present LHC collimation system to the FCC-hh energy. It currently includes a dedicated betatron cleaning insertion as well as collimators in the experimental insertions to protect the inner triplets. An aperture model for the FCC-hh is defined and the geometrical acceptance is calculated at top energy taking into account mechanical and optics imperfections. Based on these studies the collimator settings needed to protect the machine are defined. The performance of the collimation system is then assessed with particle tracking simulation tools assuming a perfect machine.
