Description
An alternative lattice design for the FCC-ee collider ring has been proposed, which aims to provide large Dynamic Aperture and Momentum acceptance through the dedicated correction of higher order nonlinear terms excited by the chromaticity correction sextupoles.
A large acceptance of the machine is required to provide a sufficient beam lifetime and good injection efficiency, which are both key components in achieving the target luminosity.
Moreover, compared to the baseline lattice, the new lattice design also simplifies the powering scheme of the arc-sextupoles.
In this presentation, the results of the Dynamic aperture studies using this new lattice are presented and compared to the baseline lattice.
