Description
The Future Circular lepton Collider (FCC-ee) is a proposed e+e− collider covering a beam energy range from 45.6 GeV to 182.5 GeV. In Z-mode operation, it will achieve the highest luminosity ever reached by any lepton collider, with a stored beam energy of up to 18 MJ. Due to synchrotron radiation damping, the vertical beam size will shrink to a few tens of micrometers, resulting in a maximum energy density of approximately 11 GJ/mm2 in the collider ring.
To safely dispose of this intense beam, a dedicated beam dumping system is essential. A transfer line is designed to increase the beam transverse size and thus lower the energy density at the dump. This contribution presents the design of the FCC-ee collider dump transfer line, excluding the absorber block, and highlights key aspects of machine protection and operational safety.
