При этом учтено вращение спина под действием Электрического Дипольного Момента (ЭДМ) и Магнитного Дипольного Момента (МДМ) с компенсацией МДМ-вращения. Получены основные характеристики структуры, такие как направление инвариантной оси и частота спин-прецессии. Рассмотрены спиновые характеристики идеальной структуры и структуры с ошибками выставки элементов, такими как поворот магнитов вокруг продольной оси.</p></abstract><trans-abstract xml:lang="en"><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. Keywords: spin-orbital dynamics, spin resonance, frozen spin, quasi-frozen spin, spinor algebra, electric dipole moment</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спин-орбитальная динамика</kwd><kwd>спиновый резонанс</kwd><kwd>замороженный спин</kwd><kwd>квази-замороженный спин</kwd><kwd>спинорная алгебра</kwd><kwd>электрический дипольный момент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spin-orbital dynamics</kwd><kwd>spin resonance</kwd><kwd>frozen spin</kwd><kwd>quasi-frozen spin</kwd><kwd>spinor algebra</kwd><kwd>electric dipole moment</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данная работа выполнена при финансовой поддержке со стороны Российского научного фонда в рамках гранта РНФ 25-72-30005</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abusaif F. et al.
