Spin Dynamics in the JLEIC Alternative Pre-Booster Ring

In order to reduce the foot-print of the JLEIC ion complex, we have designed a more compact and cost-effective octagonal 3-GeV pre-booster ring half the size of the orig-inal figure-8 design. However, this new ring does not preserve ion polarization by design as the figure-8 shape, making it necessary to study the spin dynamics to find the best solution for spin correction. Different codes, Zgoubi and COSY, are used to model and simu-late the spin dynamics in the octagonal 3 GeV ring, in-cluding spin correction with Siberian snakes.

The proposed alternative design approach for the JLab-EIC (JLEIC) ion complex uses a more compact linac and pre-booster, and consolidates the electron storage ring (e-ring) as a large booster for the ions. Following a parameter study* showing the feasibility of this alternative design approach, we have adapted the e-ring lattice by adding RF sections to accelerate ion beams**. In this study, we focus on the beam formation for protons and lead ions from the linac to the pre-booster, then into the e-ring until injection to the ion collider ring. Effects such as space charge, intra-beam scattering and the need for beam cooling will determine the total accumulated charge in each ring and the time required from injection from the injector linac to collision in the collider ring.
