The requirement on the accelerator is quite demanding with luminosity in the order of 1E34/s/cm², 70\% spin polarized electrons and light ion beams, large range of center of mass energies (30-140 GeV) and collisions of electrons with a large range of ions from protons to Uranium. To implement this new collider, many interesting accelerator science questions have to be resolved which include beam-beam interaction with a large crossing angle of 25 mrad, dynamic aperture in presence of a highly constraint high luminosity interaction region, electron storage ring with an average polarization of 70\% for both spin up and spin down in the same store, and with the required high beam currents of 2.5 A electrons and up to 1 A hadrons, some interesting high intensity effects such as fast ion instability and strong transient beam loading effects. The presentation will provide an overview of the accelerator physics of the electron ion collider. PB - JACoW Publishing CP - Geneva, Switzerland ER -
