Longitudinally polarized electrons in Novosibirsk c-tau factory
We consider a scenario for achieving and preserving the longitudinal polarization of the electron beam in the Novosibirsk tau-charm factory. The storage ring for electrons will be equipped with 5 spin rotators - the so-called Siberian Snakes. These Snakes strongly reduce the spin-orbit coupling and, thus, suppress the depolarization of the electron beam caused by quantum fluctuations of the synchrotron radiation. The proposed scheme provides a high polarization degree up to 80% - 90% in the full energy range.
