The Future Circular electron-positron Collider (FCC-ee) is planned to operate with beam energies from 45.6 to 182.5 GeV and beam current from 5.4 to 1390 mA. The purpose is to study the Z-, W- and Higgs boson’s properties and the top and anti-top quarks (ttbar). Four operation points are defined for the study - the Z, W, H and ttbar working points. 

The aim of my research is the Design and optimization of superconducting radiofrequency elliptical cavity and higher-order mode couplers for the W- and H- bosons, and the ttbar operating point of the CERN future circular lepton collider (FCC-ee).
