Longitudinal and Transverse Single Bunch Instabilities Induced by Orbit Dependent Higher Order Mode Losses

摘要

In the presence of a transverse cavity impedance there is a contribution to the higher order mode losses depending on the beam position within the cavity. This part of the higher order mode losses causes longitudinal and transverse single bunch instabilities depending on the product of dispersion and closed orbit deviation in the RF section.
