Nonlinear Acceleration Mechanism of Collisionless Magnetic Reconnection
A mechanism for fast magnetic reconnection in collisionless plasma is studied for understanding sawtooth collapse in tokamak discharges. Nonlinear growth of the tearing mode driven by electron inertia is analytically estimated by invoking the energy principle for the first time. Decrease of potential energy in the nonlinear regime (where the island width exceeds the electron skin depth) is foun...

متن کاملThree-dimensional particle simulations of collisionless magnetic reconnection
[1] Three-dimensional (3-D) particle simulations are performed in a double current layer configuration to investigate the stability of current sheets and boundary layers which develop during magnetic reconnection of antiparallel fields in collisionless plasma. The strong current layers that develop near the x line remain surprisingly laminar, with no evidence of turbulence and associated anomal...
متن کاملMagnetic reconnection configurations and particle acceleration in solar flares
Numerical simulations of two types of flares indicate that magnetic reconnection can provide environments favorable for various particle acceleration mechanisms to work. This paper reviews recent test particle simulations of DC electric field mechanism, and discusses how the flare particles can escape into the interplanetary space under different magnetic configurations.
متن کاملCollisionless magnetic reconnection in space plasmas
*Correspondence: Rudolf A. Treumann, International Space Science Institute Bern, Hallerstrasse 6, CH-3012 Bern, Switzerland e-mail: [email protected] Magnetic reconnection, the merging of oppositely directed magnetic fields that leads to field reconfiguration, plasma heating, jetting and acceleration, is one of the most celebrated processes in collisionless plasmas. It requires the violation...
