Correction of the betatron coupling and closed orbit distortion at the VEPP-2000 collider

An essential condition for the round beam mode operation at the VEPP-2000 storage ring is the zero betatron coupling in the arc between two Interaction Points. To comply with this requirement the closed orbit should be corrected and the proper skew quadrupole correction system must exist. This work presents the development of the dipole and skew quadrupole correction systems for VEPP-2000. The calculations of correction of the linear betatron coupling due to solenoids are compared to the measurement results from the VEPP-2M storage ring.
