FCC-ee Dynamic Aperture Studies and Frequency Map Analysis

The FCC-ee Lepton Collider will provide e⁺e⁻ collisions in the beam energy range of 45.6 GeV to 182.5 GeV. FCC-ee will be a precision measurement tool for Z, W, H and t physics with expected luminosities of 2.07× 10³⁶ cm⁻² s⁻¹ at the Z-pole and 1.3 × 10³⁴ cm⁻² s⁻¹ at the tt⁻ threshold. In order to achieve the foreseen luminosities, a vertical β^{*} of 1 mm to 2 mm is mandatory. Dynamic aperture and frequency map analysis for the 97.75 km machine with such a squeezed accelerator optics are studied. Furthermore, effects of machine misalignments on dynamic and momentum aperture are presented and estimations for the required tolerances are given
