| Abstract | During the third run period of the CERN Large Hadron Collider (LHC), as well as for the future High-Luminosity LHC era, luminosity levelling by beta* is a key technique to control the pile-up in the high-luminosity experiments ATLAS and CMS while maintaining Landau damping through the head-on beam-beam interaction. This implies changing the machine optics in the interaction regions while keeping high-intensity beams in collision and the experimental detectors in their data taking configuration. This contribution summarizes the implementation and operational experiences obtained during the first year of operation with beta* levelling at the LHC and provides an outlook for the following years, when the beta* levelling range will be further extended. |
