Longitudinal coupled-bunch instability studies in the PS / Damerau, H (CERN) ; Ventura, L (CERN)
The main longitudinal limitation for LHC-type beams inthe PS are coupled-bunch instabilities. A dedicated proto-typefeedbacksystemusingaFinemetcavityasalongitudinalkicker has been installed [...]

Higher-Harmonic RF System for Landau Damping in the CERN PS / Damerau, Heiko (CERN) ; Lasheen, Alexandre (CERN) ; Shaposhnikova, Elena (CERN)
Longitudinal coupled-bunch instabilities after transition crossing and at the flat-top limit the intensity of LHC-type beams in the CERN Proton Synchrotron (PS). A dedicated coupled-bunch feedback for dipole oscillation modes, using a Finemet cavity as wide-band longitudinal kicker, suppresses the instabilities up to an intensity of about 2·10¹¹ particles per bunch at extraction. [...]

Improved Longitudinal Performance of the LHC Beam in the CERN PS / Damerau, Heiko (CERN) ; Desquiens, Valentin (CERN) ; Huschauer, Alexander (CERN) ; Jibar, Azeddine (CERN) ; Lasheen, Alexandre (CERN) ; Mikulec, Bettina (CERN) ; Morvillo, Michele (CERN) ; Rossi, Carlo (CERN) ; Woolley, Benjamin (CERN)
At the end of the 2018 run the intensity target for the High Luminosity LHC (HL-LHC) had just been reached at extraction from the Proton Synchrotron (PS). In the framework of the LHC Injectors Upgrade (LIU) project additional RF improvements have been implemented during the 2019/2020 long shutdown (LS2), mainly impacting the impedance of the 10 MHz, 40 MHz, and 80 MHz RF systems. [...]

Observation and Damping of Longitudinal Coupled-bunch Oscillations in the CERN PS / Damerau, H (CERN) ; Lasheen, A (CERN) ; Migliorati, M (Rome U. ; INFN, Rome ; CERN)
Longitudinal coupled-bunch instabilities pose a major limitation to the intensity and quality of LHC-type beams in the CERN Proton Synchrotron (PS). The oscillations are excited above transition energy and mainly driven by the impedance of the main accelerating cavities at around 10 MHz. [...]

Longitudinal Coupled-Bunch Oscillation Studies in the CERN PS / Damerau, H (CERN) ; Hancock, S (CERN) ; Paoluzzi, M (CERN) ; Migliorati, M (Rome U. ; CERN) ; Ventura, L (Rome U. ; CERN)
Longitudinal coupled-bunch oscillations are an important limitation for the high-brightness beams accelerated in the CERN PS. Up to the present intensities they are suppressed by a dedicated feedback system limited to the two dominant oscillation modes. [...]
