Dynamic Aperture Studies for HL-LHC with beam-beam effects

Various possible operational scenarios are foreseen for the High Luminosity Large Hadron Collider (HL-LHC). In this note we summarize the study and characterization of the beam-beam effects for various possible operational scenarios for the High Luminosity Large Hadron Collider (HL-LHC). As an out-come of the study an optimum operational scenario for the HL-LHC is proposed based on dynamic aperture studies and reducing to the minimum the impact of the non-low beta insertions known as the experiments LHCB and ALICE. The impact of the magnets multipolar errors together with other non-linearities is quantified. The Dynamical Aperture (DA) results are used to determine the stability thresholds, while Frequency Map Analysis (FMA) is used to better understand the physical mechanisms. A description of the modification to the Sixtrack code to model the HL-LHC scenarios are also described.
