Web7 mrt. 2024 · Roughly speaking, there are two modes of ion reflection (Gedalin 2016 ). The "electric reflection" occurs when an ion cannot overcome the cross-shock potential so that their vx = 0 at some point inside the ramp. These ions have low velocities along the shock normal at their entry into the ramp.
