| Abstract: | The current to a negative probe in an argon plasma jet shows a strong dependence on probe bias and is up to an order of magnitude less than the usual convection/diffusion saturation current. The current is also in surprisingly good agreement with the calculated sheath/convection current. The results are attributed to electron?ion recombination in the vicinity of the probe. |
