Impedance simulations and measurements on the LHC collimators with embedded beam position monitors

Nicolas Frank Mounet, Benoît Salvant, Nicolò Biancacci

The LHC collimation system is a critical element for the safe operation of the LHC machine. The necessity of fast accurate positioning of the collimator's jaws, recently introduced the need to have button beam position monitors directly embedded in the jaw ...

Operational performance of the CERN injector complex with transversely split beams

Guido Sterbini, Cedric Jean-François Hernalsteens, Benoît Salvant, Massimo Giovannozzi, Hannes Bartosik

With the progress made in 2015, the beams produced by the CERN Proton Synchrotron using multiturn extraction (MTE) have been delivered to the Super Proton Synchrotron (SPS) for the fixed-target physics run. Operation successfully started in the second half ...

IMPEDANCE EFFECTS IN THE CLIC DAMPING RINGS

Nicolas Frank Mounet, Eirini Koukovini Platia, Benoît Salvant, Giovanni Rumolo

Due to the unprecedented brilliance of the beams, the performance of the Compact Linear Collider (CLIC) damping rings (DR) is affected by collective effects. Single bunch instability thresholds based on a broad-band resonator model and the associated coher ...

Electromagnetic Modeling of C Shape Ferrite Loaded Kickers

Carlo Zannini, Benoît Salvant, Giovanni Rumolo

The kickers are major contributors to the CERN SPS beam coupling impedance. As such, they may represent a limitation to increasing the SPS bunch current in the frame of an intensity upgrade of the LHC. In this paper, analytical approach and CST Particle St ...

Update of the SPS Impedance Model

Nicolas Frank Mounet, Carlo Zannini, Benoît Salvant

The beam coupling impedance of the CERN SPS is expected to be one of the limitations to an intensity upgrade of the LHC complex. In order to be able to reduce the SPS impedance, its main contributors need to be identified. An impedance model for the SPS ha ...

The SPS kickers are major contributors to the SPS transverse beam coupling impedance. The current ”flat chamber” impedance model for a kicker is obtained by applying form factors to the theoretical impedance of an axisymmetric ferrite beam pipe. This model ...
