  Initial simulations investigating using the RHIC-EIC proton beam as the drive
beam in a plasma wakefield acceleration experiment are presented. The proton
beam enters the plasma and undergoes self-modulation, forming a series of
microbunches. These microbunches resonantly drive electron density
perturbations within the plasma, exciting a longitudinal electric field with
accelerating gradients in excess of $\mathrm{GVm^{-1}}$. Injecting electrons
into the resulting wakefield offers an efficient method for accelerating
electron bunches for use in the proposed EIC collider.
