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 …

Injection in the LHC is a delicate moment, since the LHC collimation system cannot offer
adequate protection during beam transfer. For this reason, a complex chain of injection …

The LHC collimation system is implemented in phases, in view of the required extrapolation
by 2-3 orders of magnitude beyond Tevatron and HERA experience in stored energy. All …

Magnets are at the core of both circular and linear accelerators. The main function of a
magnet is to guide the charged particle beam by virtue of the Lorentz force, given by the …

The goal for 2011 is to deliver an integrated luminosity of one inverse femtobarn to the
experiments. This will require to gain an order of magnitude in peak luminosity, ie run with …

Many collective effects were observed in 2010, first when the intensity per bunch was
increased and subsequently when the number of bunches was pushed up and the bunch …

A full-scale prototype of the Large Hadron Collider (LHC) collimator was installed in 2004 in
the CERN Super Proton Synchrotron (SPS) and has been extensively used for beam tests …

The LHC phase 2 collimation project aims at gaining a factor ten in cleaning efficiency,
robustness and impedance reduction. From the impedance point of view, several ideas …

Beam tests with a large hadron collider (LHC) prototype collimator were performed at the
super proton synchrotron (SPS) in autumn 2006. Applying a new collimator control system …

The prediction of the resistive wall transverse beam impedance at the first unstable betatron
line (8 kHz) of the CERN Large Hadron Collider (LHC) is of paramount importance for …
