Ion dynamics during magnetic reconnection — •Kian Rahbarnia1, Olaf Grulke1, and Thomas Klinger1,2 — 1Max-Planck-Institut für Plasmaphysik, EURATOM Assoziation, Greifswald — 2Ernst Moritz Arndt-Universität Greifswald
Magnetic reconnection is suggested to play an important role in plasma heating by conversion of magnetic field energy into kinetic particle energy. In this context the electrons in the forming current sheet gain energy by Ohmic heating, while the ions are thought to be heated mainly inside the reconnection outflow in the downstream regions. The detailed mechanism of converting magnetic field energy into particle heating remains a field of intense research.
In the linear magnetic reconnection experiment VINETA II two axial wires parallel to a uniform magnetic guide field create a figure-eight in-plane magnetic field with a X-line along the central axis. The characterization of the perpendicular ion movement is done via Mach probes and Laser induced fluorescence measurements. Effects of the ratio of guide field to in-plane field on ion heating processes are studied.
