Abstract <p>The storage ring lattice of the quasi-frozen spin type consisting of magnetic elements and Wien filters is considered. In this case, the spin rotation under the action of the Electric Dipole Moment (EDM) and the Magnetic Dipole Moment (MDM) with compensation for the MDM rotation is taken into account. The main characteristics of the structure such as the direction of the invariant spin axis and the spin precession frequency are derived. The spin characteristics of the ideal structure and the structure with misalignments of elements such as the rotation of magnets around the longitudinal axis are considered.</p>
