Self-polarizing electron ring for eRHIC project

We present the electron storage ring for an arrangement of electron–proton and electron–ion collisions at RHIC. High degree of radiative electron polarization will be achieved at the beam energy range 5–10 GeV with characteristic time about 10 min. Required luminosity of polarized e–p collisions for studies of deep inelastic scattering is 1×1033 cm−2 s−1 in the SCM energy range 15–100 GeV.
