p-ring: Helical spin rotator like being used already at two RHIC experiments
Summary:
The design is based on the construction of a self-polarizing electron ring.
Polarized e-p and unpolarized e-ion beam collisions in the center of mass energy range of 30-100 Gev and at luminosities up to 0.9x1033 cm-2s-1 for e-p and 0.9x1031 cm-2s-1 for e-Au collisions.
The electron polarization time of 8-15min is achieved with superbend magnets.
The collider design could be realized using the present level of the accelerator technology.
