Nitrogen and nitrogen-helium gas mixture plasma was continuously generated in a rarefied gas wind tunnel as a supersonic plasma jet. We experimentally examined its acceleration phenomena and potential drop along the open magnetic field line flowing supersonically. We found that admixture of nitrogen into helium increases the flowing velocity and moderates the potential drop.
