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. The performances of the HOM damped cavities are finally evaluated using various numerical methods.<eng> vorgelegt von Shahnam Gorgi Zadeh GutachterInnen: Ursula van Rienen (Universität Rostock) ; Herbert De Gersem (Technische Universität Darmstadt) ; Rama Calaga (CERN, Geneva, Switzerland) Dissertation Universität Rostock 2021 530 621.3 539.73 530 http://purl.uni-rostock.de/rosdok/id00003023 https://doi.org/10.18453/rosdok_id00003023 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00003023-0 https://d-nb.info/1293663530/34 Accelerating cavity and higher order mode coupler design for the Future Circular Collider--(DE-627)1757776923 urn:nbn:de:gbv:28-rosdok_id00003023-0 doi: 10.18453/rosdok_id00003023 oclc: 1250313104 ppn: (DE-627)1757655212
