论文摘要
正如欧洲高能量物理学战略小组建议的，未来的循环撞机研究正在探索LHC后时代的圆形壁产品的可能设计。一种选择是FCC-HH，这是一种质子 - 质子对撞机，质量为100 TEV。实验插入区域是定义对撞机性能的关键领域。 This paper presents the first insertion region designs with a complete assessment of the main challenges, as collision debris with two orders of magnitude larger power than current colliders, beam-beam interactions in long insertions, dynamic aperture for optics with peak $β$ functions one order of magnitude above current colliders, photon background from synchrotron radiation and cross talk between the insertion regions.还提出了一种避免使用对性能影响较小的蟹腔的替代设计。
The Future Circular Collider study is exploring possible designs of circular colliders for the post-LHC era, as recommended by the European Strategy Group for High Energy Physics. One such option is FCC-hh, a proton-proton collider with a centre-of-mass energy of 100 TeV. The experimental insertion regions are key areas defining the performance of the collider. This paper presents the first insertion region designs with a complete assessment of the main challenges, as collision debris with two orders of magnitude larger power than current colliders, beam-beam interactions in long insertions, dynamic aperture for optics with peak $β$ functions one order of magnitude above current colliders, photon background from synchrotron radiation and cross talk between the insertion regions. An alternative design avoiding the use of crab cavities with a small impact on performance is also presented.
