Stereoscopic Investigation of Particle Chains in Dusty Plasmas — •Daniel Maier, Michael Himpel, Stefan Schütt, and André Melzer — Institut für Physik der Universität Greifswald, Greifswald, Deutschland

In dusty plasmas under microgravity conditions stable chains of charged dust particles can be observed. These chains are stabilized by an outward ion stream and appear near the mid-plane and around the particle free zone (void) of the plasma. So far only 2-dimensional investigations of these chains have been done, with difficulties in proofing the authenticity of a chain, observing it at full length or separating chains from each other. The use of our experimental set-up, with four high-speed cameras allows stereoscopic, 3-dimensional observation and investigation of chains and the interaction of the included particles with high temporal resolution. Here first results of these investigations will be shown.
