The ambipolar diffusion and argon ion mobility as functions of the reduced electric field and pressure times the tube radius are investigated in a weakly ionized non-uniform glow discharge plasma system. In particular, the variable cross section at the same discharge tube on the ambipolar diffusion coefficient shows a more noticeable effect than the effects from the ion mobility. As the diffusion length Lambda increases, the ambipolar diffusion D-a increases. However, it decreases as the discharge current is increased.
