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 ...

Geometric beam coupling impedance of LHC secondary collimators

Nicolas Frank Mounet, Benoît Salvant, Alexej Grudiev

The High Luminosity LHC project is aimed at increasing the LHC luminosity by an order of magnitude. One of the key ingredients to achieve the luminosity goal is the beam intensity increase. In order to keep beam instabilities under control and to avoid exc ...

Impedance model of the CERN SPS and aspects of LHC single-bunch stability

Benoît Salvant

Upgrades of the CERN particle accelerators complex are planned to increase the potential of physics discovery in the LHC. In this respect, the beam coupling impedances of the SPS and LHC are expected to be among the limitations to the intensity upgrade sch ...

Comparison between laboratory measurements, simulations, and analytical predictions of the transverse wall impedance at low frequencies

Nicolas Frank Mounet, Benoît Salvant

The prediction of the transverse wall beam impedance at the first unstable betatron line (8kHz) of the CERN Large Hadron Collider (LHC) is of paramount importance for understanding and controlling the related coupled-bunch instabilities. Until now only nov ...
