Creating nanodust clouds with different electrode geometries — •Franko Greiner, Andreas Petersen, and Alexander Schmitz — Institut für Experimentelle und Angewandte Physik, Christian-Albrechts-Universität Kiel
In a radio-frequency driven parallel plate reactor, nanodusty plasmas are created by means of reactive argon acetylene or argon silane plasmas. Switching off the reactive gas admixture creates a pure dusty plasma, consisting only of electrons, ions, and dust with a predeterminable radius. Using Mie polarimetry, Video aided extinction measurements (VAEM), and dust density wave diagnostic (DDW-D), the nanodusty plasma can be fully diagnosed [1]. For our standard setup of 60 mm circular electrodes with a 32 mm electrode gap we found dust densities of up to 6· 1013 m−3, creating a strongly electron-depleted plasma. We investigate the impact of different electrode geometries on the dust and plasma parameters of the created nanodusty plasmas. [1] A.
