Abstract

The first direct observation of a highly supersonic ion beam on the low potential side of a current-free double layer was presented. It was found that the beam shows its presence over the entire plasma source diameter. An electron beam was also observed on the high potential side. Results show that a depression in the total ion flux just downstream of the double-layer is also present.
