| Abstract | Nonlinear optics errors in low-β* insertions pose a serious challenge to successful operation of the HL-LHC. LHC experience however has demonstrated that the previously assumed correction strategy, based upon ideal compensation of selected nonlinear resonances, as determined from magnetic measurements, suffers from several limitations. A beam-based correction approach yielded a positive operational impact in the LHC, and dedicated machine studies have helped establish new methods for nonlinear optics corrections in HL-LHC. |
