Description
The FCC-ee low-energy machine, operating at 45.6 GeV, is the most affected by the collective effects because of the lowest beam energy combined with the highest beam current, the lowest emittances and the longest damping times. The design of this machine is still in progress, and the coupling impedance budget is continuously evolving in parallel with the updates of the vacuum chamber components. Correspondingly, the collective effects and instability thresholds need constant revision. In this contribution, several scenarios related to the single-beam impedance-induced collective effects are presented together with an analysis of the interplay between different tools used to mitigate possible instabilities.
