Abstract: The coupling correction system of the future SKIF light source has been optimized with the use of numerical simulation. It includes 128 BPMs (out of 224), 128 skew-quadrupoles out of 256 in MBA sections and 32 skew-quadrupoles in dispersion-free intervals. The system is complementary to the global correction and is intended to suppress simultaneously vertical dispersion and linear difference resonance. High efficiency of the EVD-based correction method has been demonstrated at various numerical examples. The possibility of determining the width of the linear difference resonance, which is necessary for such a correction, by the slope of the ellipses of normal modes is under study. The modes are resonantly swung and their elliptical shape is reproduced according to the TbT (turn-by-turn) data of the BPMs. The results of the corresponding real experiment on VEPP-4M are presented, as well as the numerical experiment on the swing of eigenmodes on the SKIF.
