Experimental Investigation of Magnetic Flux Tubes — •Jan Tenfelde, Holger Stein, Thomas Tacke, and Henning Soltwisch — Institut für Experimentalphysik V - AG Laser- und Plasmaphysik, Universitätsstr. 150, 44780 Bochum

The FlareLab experiment is designed to investigate the evolution of arch-shaped magnetic flux tubes. Recently, the experimental setup has been modified following the model considerations proposed by Titov and Demoulin in order to reproduce a certain class of solar phenomena. First results obtained with the improved plasma source are presented: differences of the magnetic topology as compared to a previous plasma source design are shown; the corresponding influence on the discharge evolution is investigated. The phenomenon of pronounced striations perpendicular to the current channel is presented, which appears to be damped by an axial magnetic field.
