Comparison of coaxial higher order mode couplers for the CERN Superconducting Proton Linac study / Papke, Kai (CERN) ; Gerigk, Frank (CERN) ; Van Rienen, Ursula (IAE)
Higher order modes (HOMs) may affect beam stability and refrigeration requirements of superconducting proton linacs such as the Superconducting Proton Linac, which is studied at CERN. Under certain conditions beam-induced HOMs can accumulate sufficient energy to destabilize the beam or quench the superconducting cavities. [...]
