Accelerating cavity and higher order mode coupler design for the Future Circular Collider

Shahnam Gorgi Zadeh
This thesis takes the first steps towards a detailed design for the large RF system of the lepton collider version of the Future Circular Collider (FCC-ee). First, this thesis investigates a suitable baseline option for the RF system of FCC-ee. This includes the search for an appropriate RF frequency and number-of-cells per cavity for each working point of FCC-ee. RF accelerating cavities and higher order mode (HOM) couplers are then designed based on the requirements of each operation energy.
