Results are presented from two dimensional hybrid simulations of curved collisionless supercritical shocks, retaining both quasi‐perpendicular and quasi‐parallel sections of the shock in order to study the character and origin of the foreshock ion population. The simulations demonstrate that the foreshock ion population is dominated by ions impinging upon the quasi‐parallel side of the shock, while nonlocal transport from the quasi‐perpendicular side of the shock into the foreshock region is minimal. Further, it is shown that the ions gain energy by drifting significantly in the direction of the convection electric field through multiple shock encounters.
