Abstract

The time development of a supersonic argon beam generated by a current-free double-layer (DL) was obtained. The study was carried out by pulsing a 'helicon discharge' and measuring the total ion current and ion beam current during the first few milliseconds using a retarding field energy analyzer. The ion beam current was observed during the plasma breakdown phase and was stable thereafter. A comparison between the DL case and a higher pressure 'non DL case led to the conclusion that the double-layer is formed at ∼ 100 μs.
