Study of Different Operating Modes of the 4th RF Harmonic Landau Damping System in the CERN SPS

To study possible cures for multi-bunch instabilities observed with the present high intensity proton beam in the SPS, a fourth harmonic RF system was used during acceleration in bunch lengthening and bunch shortening modes of operation. The latter mode was found to be more efficient in controlling...

Sumario:To study possible cures for multi-bunch instabilities observed with the present high intensity proton beam in the SPS, a fourth harmonic RF system was used during acceleration in bunch lengthening and bunch shortening modes of operation. The latter mode was found to be more efficient in controlling beam stability. We present an analysis of possible reasons.
