Particle Chains in Dusty Plasmas under microgravity — •Daniel Maier, Michael Himpel, Stefan Schütt, and André Melzer — Institut für Physik der Universität Greifswald, Greifswald, Deutschland
Chain-like structures of charged dust particles have been observed in dusty plasmas under microgravity conditions. These structures appear near the mid-plane and around the particle free zone (void) of the plasma. The previous 2-dimensional investigations of the chains have difficulties in separating chains from each other, proofing their authenticity or observing them at full length. The described experimental set-up, containing four high speed cameras allows a stereoscopic, 3-dimensional observation and investigation of these structures and the interaction of the included particles with high temporal resolution (up to 200 fps). Here a simple model to identify chains and first results of the stereoscopic investigations will be shown.
