Abstract :
An investigation is presented of the longitudinal and transverse multibunch instabilities based on an assumed frequency shift behavior during tuning of the remaining parasitic modes of an ELETTRA cavity prototype equipped with higher order mode (HOM) suppressor(s). A comparison is made with similar results from the undamped cavity. The goal of the analysis is to provide information about the importance of these HOMs and to define (if necessary) shunt impedance thresholds below which no multibunch instabilities occur.<>
