abstract = {We experimentally study the characteristics of supersonically flowing helium plasma along a mirror and cusp magnetic field, including the flow direction along open field lines. The plasma is initially generated by arc discharge under atmospheric pressure, followed by a supersonic expansion into a weak uniform longitudinal magnetic channel in a rarefied gas wind tunnel as a plasma expansion chamber, and finally, expanded along the mirror or cusp magnetic field. Along the mirror type magnetic field, the plasma forms a high potential region around the plasma boundary and a low potential region around the axis of the plasma. For the cusp type, we observed a dark region, which is considered to be a shock wave.},
