Measurement and identification of HOM`s in RF cavities
Conference
·
OSTI ID:539517
One of the major sources of beam impedance in accelerators is the higher-order modes (HOM`s) of the RF cavities. We report here on a number of techniques for the identification of HOM`s and measurement of their properties. Central to these techniques is the application of symmetry principles and the effects of symmetry-breaking perturbations (including mode-mixing) to the {open_quotes}standard{close_quotes} techniques of spectrum measurements and bead pulls.
