The AWAKE experiment at CERN [1] recently demonstrated the world's first acceleration of electrons in a proton-driven plasma wakefield accelerator [2]. Such accelerators show great promise for a new generation of linear e-p colliders using GV/m accelerating fields. Effectively driving a wakefield in AWAKE requires 100-fold self-modulation of the 12 cm Super Proton Synchrotron (SPS) proton beam using a plasma-driven process which must be carefully controlled to saturation [3,4]. Previous works have modeled this process assuming cylindrical symmetry of the transverse space and momentum profiles of the proton bunch. In this work, 3D particle-in-cell simulations are used to investigate the self-modulation of non-round beams. Implications of such effects for effectively sustaining resonant wakefields are discussed.
