Workshop on LHC Interaction Region Correction Systems

The performance of the Large Hadron Collider (LHC) at collision energy is limited by the field quality of the interaction region (IR) quadrupoles and dipoles. This workshop will bring together CERN, FNAL, KEK , BNLand other interested personnel to address Interaction Region magnet field quality issues, to review the principle and efficiency of correction and compensation schemes, and to finalize a compensation plan and corrector layout for the LHC Interaction Region. The workshop scope will cover FNAL and KEK built quadrupoles, BNL built separation dipoles, and European Interaction Region correctors.
