Description
The Future Circular electron–positron Collider (FCC-ee), with a circumference of approximately 90 km, is designed to push both the luminosity and energy frontiers for high-brightness lepton beams. The unprecedented stored beam energy, reaching up to 17.5 MJ -- around two orders of magnitude greater than in any previous lepton collider -- poses major challenges for safe operation. Uncontrolled losses could result in high experimental backgrounds, downtime, or even damage to accelerator components, making an efficient and reliable collimation system essential.
Two layouts and optics configurations are currently under consideration for the FCC-ee: the Global Hybrid Correction (GHC) and the Local Chromaticity Correction (LCC) schemes. While a collimation concept has previously been proposed for the GHC optics, this paper presents a new collimation layout specifically designed for the LCC lattice. The collimation performance is then compared between the two optics and layout versions under representative loss scenarios to identify in which optics the collimation system works best.
