Description
The goals of this 1-day CARE-HHH working meeting on "LHC Beam-Beam Compensation & Beam-Beam Effects for the LHC Upgrade" are to develop an implementation plan for wire compensation at the LHC, and to study beam-beam effects in the LHC luminosity upgrade perspective, including the large Piwinski angle regime, the impact of a few encounters at reduced distance, and options for a crab-waist scheme in the LHC.
