Abstract We have investigated the robustness of the spin-navigator based method for manipulating the beam polarization to bend magnet installation errors. Toward that end, variation of the invariant spin axis components along the beamline of an imperfect storage ring operating in the spin-transparent mode has been estimated. The beam polarization vector behavior in the given lattice has been investigated. Conclusions are made regarding the feasibility of using “spin navigator” solenoids for defining the beam polarization axis in the detector region.
