Title: Magnetic Measurements of the Correction and Adjustment Magnets of the Main Ring
Abstract:Correction magnets correct the field imperfections and alignment errors of the main quadrupoles and bend magnets.For reducing a.nd controlling chromaticity there are 186 sextupoles a.nd 78 octupoles, ...Correction magnets correct the field imperfections and alignment errors of the main quadrupoles and bend magnets.For reducing a.nd controlling chromaticity there are 186 sextupoles a.nd 78 octupoles, while for suppressing various resonances there are 12 normal and 18 skew sextupoles and 24 normal and 18 skew quadrupoles.Beam positions are individually controlled by 108 horizontal and 108 skew dipoles.This report includes results of the all Main Ring correction and adjustment magnet harmonic measurements.The measurement principle and basic equations are described in Appendix 1.Read More
