ICCD-Measurements of rf-discharges in the Zyflex chamber — •Baldo Bán Kabuß, Christina Knapek, and André Melzer — Institute of Physics, University of Greifswald, 17489 Greifswald, Germany

In dusty plasmas the properties of the discharge strongly affect how clouds of embedded microparticles behave. Usually forces created by the plasma induce a large void in the center of the dust cloud. The Zyflex chamber is a device with four independent rf electrodes which is capable of creating homogeneous dust clouds under microgravity conditions. In this contribution the shape and intensity of the plasma glow is observed on a nanosecond time scale using a very light-sensitive ICCD-camera. From this data the spatially and time resolved excitation is calculated. The investigation allows deeper understanding of how phase and/or amplitude differences between electrodes change the plasma and thus affect dust cloud shape and structure.
