Higher-order modes (HOMs) may affect beam stability and refrigeration requirements
of superconducting proton linacs such as the SPL which is being studied at CERN. One
option being considered to limit these effects is the use of coaxial HOM couplers.
In this work, potentially dangerous modes are analyzed and corresponding damping requirements
derived. The design process of coaxial HOM couplers is examined under new aspects.
Several prototypes are elaborated and compared in terms of mode damping, thermal loads,
structural deformations, mechanical tolerances, and multipacting.

Moden höherer Ordnung (HOMs) können beträchtlich die Strahldynamik und Kühlanforderungen
supraleitender Linearbeschleuniger, wie dem am CERN untersuchten SPL, beeinflussen.
Koaxiale HOM Koppler sind eine Möglichkeit, um Auswirkungen entsprechender Moden zu
begrenzen. Im Rahmen dieser Arbeit wurden potentiell gefährliche Moden analysiert
und Dämpfungsanforderungen abgeleitet. Der Kopplerentwurf wurde unter neuen Gesichtspunkten
aufgegriffen. Verschiedene Prototypen wurden bezüglich Modendämpfung, thermisches
Verhaltens, strukturmechanischer Verformungen, Toleranzen und Multipactings verglichen.
