چکیده انگلیسی
Split resonances are a common appearance in superconducting cavities and are studied here on a specific example. A five cell superconducting cavity suitable for the envisioned electron-hadron collider eRHIC was designed and will be used in the upcoming “Coherent electron Cooling” Proof-of-Principle experiment. The superconducting cavity is intended for high-current applications, and beam stability depends on minimizing the Higher Order Modes (HOM). This was attempted in the design phase and will be done with appropriate mode dampers in operation. The design was implemented as a copper cavity and two Niobium cavities were fabricated. The availability of the copper model provided a convenient opportunity to confirm the design and to study potentially nefarious HOMs. Selected high-Q resonances were investigated via bead pull measurements. The appearance of split resonances impeded their study and suitable methods of HOM identification are presented in this report.
