Description
Longitudinal polarization of electron beam in the interaction point is an essential requirement for designs of electron-ion colliders developed in BNL and JLab. In electron energy range of these colliders the spin rotators on the basis of interleaved solenoidal and dipole magnets presents a most realistic design choice. But, the rotator insertions have to be spin-matched in order to minimize depolarization caused by stochastic effect of synchrotron radiation. The talk presents and discusses the optics conditions required for spin matching of solenoidal spin rotators, as well as possible realizations of these conditions in the interaction region lattice.
