Abstract
The FCC-ee, with its unprecedented luminosity goal and high energy reach, creates challenges and requires solutions to many issues in order to produce a realistic design for the complex machine detector interface. The interaction region design for the FCC-ee adopts the crab-waist collision scheme and proposes an elegant local chromaticity correction system. An asymmetric layout of nearby dipoles suppresses the critical energy of synchrotron radiation incoming to the detector at the interaction point to a maximum value of 100 keV. The main challenge of the FCC-ee machine detector interface design is to combine the many conflicting accelerator and 2 T detector constraints, aiming for the optimal trade-off choices that simultaneously allow for a best machine performance in terms of integrated luminosity and data taking efficiency. Much of the success of the FCC-ee will be related to the interaction region design, as a result of the ingredients coming from areas of accelerator physics, mechanical engineering and detector optimization.
Highlights
The Future Circular Collider (FCC-ee) [1] aims to make precision studies and rare decay observations in the range of 90 to 365 GeV centre-of-mass energy
The unprecedented ring circumference of − 100 km allows for a target luminosity per IP of 2 × 1036 cm−2 s−1 at the Z pole and the ability to reach the ttenergy with 1.8 × 1034 cm−2 s−1 luminosity
Plus (2021) 136:1068 operation modes have an immediate impact on the interaction region (IR) optics as well as on the machine detector interface (MDI) design that is unique for all running energies
Summary
The Future Circular Collider (FCC-ee) [1] aims to make precision studies and rare decay observations in the range of 90 to 365 GeV centre-of-mass energy. This energy range will allow precision measurements of the Z and W bosons with unique accuracy as well as exploring the high energy frontier up to the Higgs boson and top quark. The Z pole run will be characterized by the demand for high luminosity, requiring a high beam intensity operation mode. J. Plus (2021) 136:1068 operation modes have an immediate impact on the interaction region (IR) optics as well as on the machine detector interface (MDI) design that is unique for all running energies. While pointing out the challenges for the different aspects of this design, we discuss the ongoing work and our plan for further studies
