Complex Plasmas in the Einstein Elevator — •Andreas Schmitz¹, Michael Kretschmer¹, Christoph Lotz², and Markus Thoma¹ — ¹I. Physikalisches Institut, Justus-Liebig-Universität, Gießen, Germany — ²Instititut für Transport- und Automatisierungstechnik, Gottfried Wilhelm Leibniz Universität Hannover

An experiment with complex plasmas was conducted in a copy of the former International Space Station Plasmakristallexperiment-Nefedov laboratory in the University of Hannover's drop tower, the Einstein Elevator. For the experiment performed, an argon high-frequency plasma was generated in the plasma chamber at low pressures into which melamine-formaldehyde microparticles were injected. When the setup was dropped inside the Einstein elevator, the microparticles underwent an instantaneous transition from 0 g to 1 g and were subsequently lifted from the sheath region into the bulk plasma during the microgravity phase. The first results of the analysis of this experiment are presented here.
