Description

The electron–positron Future Circular Collider (FCC-ee)
is a proposed lepton collider for high-energy particle physics
as a possible successor of the Large Hadron Collider (LHC).
The extremely tight emittance and beam stability require-
ments of the FCC-ee make the control of time-dependent
magnetic field variations critical. Power supply ripples in-
troduce fluctuations in the magnetic field of accelerator mag-
nets, which translate into turn-by-turn orbit and tune modu-
lations, potentially leading to emittance growth and beam
degradation. In this context, single-particle tracking simu-
lations are used within the Xsuite simulation framework to
assess the impact of such noise on beam quality in view of
defining power converter specifications.
