Experimental Simulation of Solar Flares — •Henning Soltwisch¹, Lukas Arnold², Jürgen Dreher¹, Holger Stein¹, and Jan Tenfelde¹ — ¹Ruhr-Universität Bochum — ²Forschungszentrum Jülich

In this contribution a custom-built laboratory experiment will be introduced, which is aimed at detailed studies into the behavior of plasma configurations with initially loop-shaped magnetic field lines under the influence of driving boundary conditions. In its first version, the set-up has been used to reproduce and extend previous studies of Bellan et al. (Phys. Plasmas 5 (1998), 1991). At present, the device is re-designed to mimic a model that was proposed by Titov and Demoulin (Astron. Astrophys. 351 (1999), 707) to investigate twisted magnetic configurations in solar flares. The observed dynamics of the magnetic flux tubes will be analysed by means of extensive 3-dimensional MHD simulations in order to determine the influence of parameters like, e.g. the initial magnetic field geometry on magnetic stability.
