First Experiments on Dusty Plasmas in the D-Mag Magnet — •Andre Melzer1, Matthias Mulsow2, Harald Krüger1, Stefan Schütt1, and Michael Himpel11Institute of Physics, University of Greifswald — 2IPP Greifswald

In the past years the study of dusty plasmas under strong magnetic fields has gained increased interest. Dusty plasmas consist of nanometer to micrometer sized particles that acquire high negative charges due to the inflow of plasma electrons and ions. To reveal magnetization effects of the dust species high magnetic field strengths are required.

In Greifswald, recently, the D-Mag magnet has been installed that allows to generate homogeneous magnetic fields up to 6 T. Experiments at these field strengths have been performed using micrometer-sized dust particles. First results will be presented. Despite the strong field, magnetization of the dust species is not expected due to its large mass. However, electrons and ions will be magnetized and the influence of these magnetized plasma species on the dust will be investigated.
