Description:
Nature Physics 12, 263 (2016). doi:10.1038/nphys3578 Authors: Rongsheng Wang, Quanming Lu, Rumi Nakamura, Can Huang, Aimin Du, Fan Guo, Waileong Teh, Mingyu Wu, San Lu & Shui Wang Magnetic reconnection is an important process in space and laboratory plasmas that effectively converts magnetic energy into plasma kinetic energy within a current sheet. Theoretical work suggested that reconnection occurs through the growth and overlap of magnetic flux ropes that deconstruct magnetic surfaces in the current sheet and enable the diffusion of the magnetic field lines between two sides of the sheet. This scenario was also proposed as a primary mechanism for accelerating energetic particles during reconnection, but experimental evidence has remained elusive. Here, we identify a total of 19 flux ropes during reconnection in the magnetotail. We found that the majority of the ropes are embedded in the Hall magnetic field region and 63% of them are coalescing. These observations show that the diffusion region is filled with flux ropes and that their interaction is intrinsic to the reconnection dynamics, leading to turbulence.
