Description
A comprehensive impedance model is essential to ensure beam stability and optimize performance in the FCC-ee main rings. In this talk, we present the current status of the impedance budget, developed as part of the ongoing FCC-ee design studies. The model includes contributions from a wide range of components — including beam pipe, collimators, bellows, tapers, RF cavities and beam position monitors — and accounts for both resistive wall and geometric effects. We also address the specific challenges posed by the unique characteristics of FCC-ee, together with recent advancements in simulation tools and methodologies. Finally, we discuss the criteria adopted to define and structure the impedance budget.
