Modeling Coupling and Its Correction in Siberian Circular Photon Source

AbstractUsing the MADX options, the stages of orbit correction and then optics correction were simulated, taking into account the specified tolerances for the positioning of magnetic elements and girders in the Siberian Circular Photon Source (SKIF, the Russian acronym). Numerical modeling of hte effect of residual perturbations of the guide field on the vertical emittance and vertical size of the beam has been carried out. A generalized method of skew-quadrupole coupling correction in SKIF has been developed and verified by simulation, which allows simulteneously minimizing the vertical dispersion and compensating for the linear difference coupling resonance.
