| Abstract | Measurements of the transverse beam halo in the Large Hadron Collider (LHC) provide crucial input for the performance evaluation of the collimation configuration in the High-Luminosity LHC (HL-LHC) era. Such measurements are carried out in various phases of the LHC operational cycle by scraping the beam with movable collimators. Understanding the halo population and halo formation mechanisms is crucial for optimising accelerator performance. Analysis of collimator scan data allows the evaluation of future needs for active halo depletion mechanisms at the HL-LHC, or other ways of mitigating halo-related risks to machine availability and protection. This contribution analyses the LHC Run 2 (2015-2018) and Run 3 (started in 2022) measurements using measured bunch-by-bunch beam intensity data. Different beam parameters are explored by profiting from upgraded beam parameters in the LHC injector complex. |
