Description
In the Future Circular Collider (FCC-ee) at CERN, lead shielding will be required on the collider arc dipoles around synchrotron radiation (SR) absorber locations to reduce radiation levels in the tunnel and protect sensitive components. The shielding assemblies will be mounted around the yokes, where scattered SR photons are expected to deposit 10-15 MW of power in total (across all absorber locations combined over the entire collider) at the tt-bar operating point. Between the yokes and the shielding, a water-cooling system will be integrated to cool both the shielding and the magnet. Recent design studies have focused on refining the geometry and cooling layout to simplify manufacturing, control costs and maintain shielding performance. A shielding prototype is planned to inform design choices and further improvements. This contribution presents the design evolution, plans for a prototype, and cooling system optimisations.
