TI - Studies and Possible Mitigation of Electron Cloud Effects in FCC-ee 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 - In this work, we present numerical results for the electron cloud build-up and mitigation studies considering Arc Dipole and Drift sections of the FCC-ee collider. We report the central electron density that could be reached by minimising secondary electron contributions and the photoelectron generation rates in order to achieve e⁻ densities lower than the single-bunch instability threshold, considering the baseline beam parameters. Additionally, simulation results revealing the behavior of electron-cloud formations for various SEY values, photoemission rates, vacuum chamber radii, and bunch spacings are included. In the last section, we discuss initial investigations to clean residual electrons after the beam pass.
