Description
The Electron-Ion Collider (EIC) is presently under construction at Brookhaven National Laboratory, and will collide electrons with an energy of up to 18 GeV with hadrons of up to 275 GeV. In this work we evaluate the feasibility of using proton-driven plasma wakefield acceleration to accelerate electron bunches to full energy for injection into the EIC Electron Storage Ring. Particle-in-cell simulations are used to identify a scheme which allows the acceleration of electron bunches with high charge and low energy spread, building on previous studies which investigated the potential energy gain.
The RHIC “BLUE RING”, which accelerates hadrons in the same direction as the electrons of the EIC, can be exploited to drive the plasma wakefields, offering the potential to significantly reduce the capital cost of the EIC facility. We show that by increasing bunch population to $3\times 10^{11}$, and moderate compression of the drive bunch to 2.5 cm, high accelerating fields can be achieved by exploiting the self-modulation of the proton beam, as harnessed by the Advanced Wakefield Experiment (AWAKE) project at CERN. To facilitate the use of a plasma discharge, we consider the possibility of using different ions, instead of rubidium.
