We present a study of the beam coupling impedance due to trapped modes of a new protection septum that will be installed in the CERN Proton Synchrotron (PS) during the Long Shutdown 1 (LS1). The interaction between the particle field and the discontinuities inside the septum generates electromagnetic fields localized in a particular region inside the device. These resonances, producing narrow peaks in the coupling impedance, can be potential source of beam instabilities for high intensity particle accelerators like PS. The final outcome of these studies is the basis for the acceptance of the septum installation in section 15 of the PS ring.

Abstract
We present a study of the beam coupling impedance due to trapped modes of a new protection septum that will be installed in the CERN Proton Synchrotron (PS) during the Long Shutdown 1 (LS1). The interaction between the particle field and the discontinuities inside the septum generates electromagnetic fields localized in a particular region inside the device. These resonances, producing narrow peaks in the coupling impedance, can be potential source of beam instabilities for high intensity particle accelerators like PS. The final outcome of these studies is the basis for the acceptance of the septum installation in section 15 of the PS ring.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
