Feasibility of kicker systems for FCC-ee and injectors

CERN’s Future Circular Collider (FCC) comprises a ~91 km circumference lepton collider and its injector complex. This contribution summarises the feasibility studies performed for the various kicker systems needed to transfer the beam between the different machines. The individual system requirements are reviewed, recent changes are highlighted, and the chosen conceptual design is outlined. Particular effort has been made to harmonise the hardware parameters across the machines to minimise the number of different beam line element types. The feasibility of the design parameters and technology options is discussed for both beam line elements and pulse generators. Early system integration aspects and implications on subsystems such as pulse transmission cables are also discussed. Consequences of the more restrictive requirements on the abort gap length in the collider are analysed. This contribution concludes with recommendations for detailed studies and prototyping required to ensure a viable parameter space for the upcoming detailed technical design phase.
