We investigated the impact of a probe on a glow plasma in a floating probe method used in a hypersonic flow. Considering the change in the cross-sectional area of the positive column suggests that the electron density in front of and behind the shock wave appear to be the same, which leads to the uniform reduced electric field along the positive column whose cross-sectional area is uniform.
