For synchrotron radiation (SR) sources - the dedicated electron (positron) storage rings - a high brightness of a photon beam represents the most interest. In turn the brightness of SR depends oppositely on the transverse phase volumes (emittances) of an electron beam as radiation source. For the given optical structure a horizontal emittance of electron beam is determined, mainly, by quantum fluctuations of SR, whilst vertical emittance is defined, basically, by a level of a coupling (width of a resonance) between vertical and horizontal betatron oscillation of particles. It is reported in the work that the control of the betatron coupling factor in SIBERIA - 2 storage ring in Kurchatov institute reaches a level of 0.001 with the use of skew-quadrupoles. Closed orbit distortions control at a micron level, an arrangement and the forces of skew - quadrupoles also are the objects of research. Experimental dependence of the electron bunch transverse sizes on the coupling factor is presented.
