Abstract
A wide world discussion have been opened few years ago about future e + e − collider after the Higgsboson discovery. Besides utterly high luminosity this machine has to operate with polarized beams. We shall overview in this paper problems and practical possibilities to satisfy second requirements of the future collider. The radiative beam polarization at this 100 km machine will be very long procedure. On other side, at the present time there are developed intensive polarized electron sources based on ArGa photo cathodes with polarization about 90 percents. We show, that fast electron synchrotron equipped pair Siberian Snake is able to provide to accelerate polarized electrons up to the top energy of the collider.
