Three-dimensional MHD simulations of the plasma gun generated flow performed with the GORGON code. Two-dimensional distributions of the plasma in yz-plane, passing through the middle of the 3D flow, are shown. Panels a and b: are at t = 6 μs, while panels c and d: are at t = 12 μs. The plasma gun is at the top, like in the experiment (see Fig. 6). The electron number densities [cm⁻³] are shown on the left in logarithmic scale, while the electron temperatures [Kelvins] are on the right. The applied magnetic field is B_x = 450 G, directed out of plane.
