Particle physics has arrived at an important moment of its history. The discovery of the Higgs
boson, with a mass of 125 GeV, completes the matrix of particles and interactions that has …

In this talk we propose possible scenarios for operation of beams during the betatron
squeeze, adjust and stable beam mode at 6.5 TeV energy for the 2015 LHC physics run …

A new type of fast luminosity separation scans (“emittance scans”) was introduced at the
CERN Large Hadron Collider (LHC) in 2015. The scans were performed systematically in …

Long-range beam-beam interactions dictate the choice of operational parameters for the
LHC, such as the crossing angle and β∗, and therefore the luminosity reach for the collider …

During the operation of the Large Hadron Collider in 2018, the majority of physics data was
collected with a beam energy of 6.5 TeV, a bunch spacing of 25 ns and with V-functions in …

The study of machine-induced background to the experiments is vital for several reasons.
Too much background can be an issue for operation and the difficult part is to judge when …

The goal of the High-luminosity upgrade of the LHC is to deliver an integrated luminosity of
at least 250 fb-1 per year (assuming at least 160 days of operation at high-luminosity) in …

This note summarised the status of the studies on the coherent beam-beam effects in the HL-
LHC project. It is shown that the obit, tune, chromaticity and dynamic β effects due to head …
