Description
The design of the Future Circular Collider electron-positron (FCC-ee) vacuum system integrates vacuum engineering, impedance mitigation, and surface physics to realise ultra-high vacuum (UHV) and low beam-coupling impedance, ensuring compatibility with high beam currents and sustained operational stability. Building on these design principles, this contribution presents an overview of the principal vacuum components and outlines the studies conducted to evaluate and optimise their electromagnetic and vacuum performance. Particular emphasis is placed on the interplay between material properties, surface treatments, and component geometry, as well as on the distribution and integration of vacuum elements and transitions within the accelerator. Impedance studies were performed to evaluate the electromagnetic impact of representative vacuum components. The main findings are summarised, highlighting the achieved performance and outlining directions for further optimisation, forming part of a continuous effort toward the development of a robust, low-impedance vacuum system that meets the stringent requirements of the FCC-ee.
