  1. 7. Overview of the accelerator issues that impact the absolute luminosity calibrations at the LHC
    Witold Kozanecki (University of Oregon (US))
    11/03/2025, 09:00
  2. 8. Sources & mitigation of non-factorization in the injectors & the LHC
    Foteini Asvesta (CERN)
    11/03/2025, 09:40

    • mechanisms of generating non-factorization in the proton-density
    distributions, and its transport through the injector chain
    • optimized beam preparation for vdM beams — how to optimize
    factorization already before the vdM fill (e.g. scraping
    measurements in LHC at injection to confirm factorization, further
    optimization of beam production schemes in the injectors
    • collimation in the LHC?
