The simulation box has a cloud in each half. The clouds collide with the speed along . The magnetic field is in the plane. The convection electric field points along and changes sign at .

The electron phase space density in the plane (a) and the ion phase space density in the plane (b). The reached by some electrons implies that their kinetic energy is comparable to that of the ions. The ion distribution reveals a forming downstream region separating a reverse shock from the forward shock, which moves to increasing . The ions of the tenuous cloud are reflected back into the upstream region within . This interval coincides with that of the strongest electron acceleration. The color scale is 10-logarithmic.

The magnetic field components (a), (b), and (c) in units of . All components show structures on ion skin depth scales within the . The and reveal a magnetic vortex with a counterclockwise sense of rotation within and with its center with at . A further quasiplanar structure in is located within . The is strongest in the interior of the vortex in the plane and its perimeter coincides with the magnetic vortex (enhanced online). [URL: http://dx.doi.org/10.1063/1.3493627.1]10.1063/1.3493627.1

The currents (a) and (b): The distribution in (b) reveals an almost circular vortex for and (periodic wrap-around). This vortex encircles an interval with a strong . The currents are correlated indicating a flow in the plane on the perimeter that is increasingly deflected along near the center. A current system is present in all components in the downstream and in (enhanced online). [URL: http://dx.doi.org/10.1063/1.3493627.2]10.1063/1.3493627.2
