Higher-Order-Mode Couplers for SPL Cavities — •Kai Papke1,2, Frank Gerigk1, and Ursula van Rienen2 — 1CERN — 2University of Rostock
Higher-Order-Modes (HOMs) may affect both beam stability and the refrigerating capacity requirements of superconducting proton linacs like for the CERN SPL. In the process of limiting the effects of these beam induced modes, it is considered to install HOM-Couplers. The full HOM spectrum for medium- and high-beta cavity types is already analyzed in order to define the damping requirements for appropriate couplers. In this work several design approaches are demonstrated and also discussed regarding to the multipacting sensitivity and thermal losses.
