Figure 5: Simulation results.
From: Formation and evolution of a pair of collisionless shocks in counter-streaming flows
(a) The spatio-temporal evolution of the electrostatic shock obtained by our PIC simulation. The left-panel shows the ions distribution and the right-panel show the electrostatic field distribution. The color bar on the left-side is the ions density normalized to the initial ions density. The color bar on the right-side is the strength of the electrostatic field. The blue-dash-line represents the shock front. The inset is the bipolar electrostatic field distribution obtained at tωpe = 1000 (b) The typical ion trajectories for free-ions, trapped-ions and reflected-ions. (c) The ions phase-space at tωpe = 6000. The monoenergetic protons are generated by the electrostatic shocks. (d) The electrons phase-space at tωpe = 6000. The overlapped black line shows the electron temperature distribution.
