The ATLAS experiment at the Large Hadron Collider employs a two-level trigger system to
record data at an average rate of 1 kHz from physics collisions, starting from an initial bunch …

A good understanding of the luminosity performance in a collider, as well as reliable tools to
analyse, predict, and optimise the performance, is of great importance for the successful …

A variety of processes can cause unavoidable beam losses during normal and abnormal
beam operation. Because of the high stored energy of about 700 MJ and the small …

This report describes the running scenario for operation with Pb-Pb and p-Pb collisions in
the HL-LHC. The expected beam parameters are described, starting from the beams …

The Large Hadron Collider (LHC) at CERN accelerates protons to an energy of 6.5 TeV and
brings them into collision at four interaction points, with a frequency of 40 MHz. Installed at …

Landau damping of coherent modes is strongly dependent on the exact shape of the particle
bunches. One often assumes that the transverse distributions in high-energy hadron …

An overview of the main LHC proton-proton program at 6.5 TeV beam energy during Run 2
is presented. The paper summarizes the highlights and the limitations during each year from …

For a two-stage collimation system, the betatron phase advance between the primary and
secondary stages is usually set to maximise the absorption of secondary particles …
