Description
The collider beam optics (GHC) has been updated since FCC Week 2024 including several changes: longer $L^*$, smaller $\beta_x^*$ (Z), higher horizontal chromaticity (Z), longer space for the RF (Zh/$t\overline t$), wider beam separation in the technical straight, installation of vertical depolarization bump (Z/W), etc. The resulting luminosity and beam lifetime basically kept unchanged.
