Current Sheet Structure in Anti-Parallel Driven Magnetic Reconnection

Solutions of the particle dynamics, the density profiles and flow structures of electrons and ions in the reconnecting current sheet during quasi-steady phase of anti-parallel driven magnetic reconnection are presented. The theory provides understanding of the particle dynamics and heating/acceleration processes as observed in the PIC simulations. In particular, the increase of ion temperature is due to the electrostatic potential drop which is proportional to the square of the upstream Alfven velocity..
