TI - FCC-ee Parameter Choice for Luminosity Optimization J2 - Proc. of eeFACT2022, Frascati, Italy, 12-16 September 2022 CY - Frascati, Italy T2 - ICFA Advanced Beam Dynamics Workshop on High Luminosity Circular e+e- Colliders T3 - 65 LA - english AB - Beam dynamics in FCC-ee will be very different from all previous e+e colliders as it will be heavily influenced by new effects (such as beamstrahlung) and new types of instabilities (such as coherent beam-beam instability and 3D flip-flop). Optimization of the main FCC-ee parameters was carried out taking into account all these factors, and this was recorded in the CDR. Another important feature of FCC-ee is the great sensitivity of the lattice and 6D dynamic aperture to misalignments and field errors. Now this problem is seen as one of the main bottlenecks limiting the luminosity. In this paper, we consider the main effects and dependencies that determine the choice of collider parameters at different energies. We will then discuss [currently known] existing problems and possible solutions. PB - JACoW Publishing CP - Geneva, Switzerland ER -
