Description
Precise regulation of the bunch population in FCC-ee is required to maintain the charge imbalance between collision bunches within the 3-5% tolerance that preserves beamstrahlung limits, bunch-length stability, and avoids flip–flop behaviour. Laser-driven Compton backscattering (CBS) has been proposed as an active actuator for bunch-by-bunch intensity control.
An Xsuite-based simulation framework is employed to track the beam over many turns, while the bunch population is continuously updated according to the CBS-induced particle removal. The modified bunch intensity is then propagated into the beam–beam interaction model, allowing the resulting impact on beam parameters and overall stability margins to be quantified.
