A concept of obtaining longitudinal polarization at the JINR tau-charm factory

Within the scopes of the JINR tau-charm factory design it is possible to provide the suitable degree of longitudinal polarization (more than 50%) by known means based on the “siberian snake” scheme with superconducting solenoids. riant is demonstrated to obtain longitudinally polarized beams in a radiative manner basing exclusively on the spin-orbital coupling mechanism of polarization.
