Filaments in (a–d) measured using shadowgraphy represent the information of plasma density, and in (e, f) measured using the Faraday method represent the path-integrated magnetic field strength. a, b Linear phase (0.5 and 1.0 ns) of WI showing that locally ordered filaments form at the midplane and stretch along the flow direction with both flows’ interpenetration. c, d Nonlinear phase (2.0 and 3.0 ns) of WI showing that filaments/currents coalesce each other and distort. e, f The typical distribution of transverse magnetic field path integral intensity (∫Bzdl) at 1 ns (b) and 3 ns (d). These images have been sharpened in postprocessing to emphasize the striations. (Raw images see Supplementary Fig. 5).
