Three-dimensional spontaneous magnetic reconnection in neutral current sheets
The reconnection of magnetic field lines is one of the fundamental processes that lead to the eruptive release of stored magnetic energy in plasmas. A large number of observations and experiments, e.g., solar flares, geomagnetic substorms, the sawtooth instability in fusion experiments, and laboratory reconnection experiments, support this hypothesis. Magnetic reconnection is important for the ...

متن کاملReview of controlled laboratory experiments on physics of magnetic reconnection
We review results from the most recent experiments in the past 2 decades in which magnetic reconnection has been generated and studied in controlled laboratory settings. As a whole, research on the fundamental physics of the reconnection process and its hydromagnetic consequences has been largely theoretical. Laboratory experiments are crucial for understanding the fundamental physics of magnet...
متن کاملMagnetic Weibel field generation in thin collisionless current sheets in reconnection in space plasma
In collisionless reconnection in space plasma like the magnetospheric tail or magnetopause current layer, magnetic fields can grow from thermal level by the action of the non-magnetic Weibel instability driven in thin (∆ < few λi) current layers by the counter-streaming electron inflow from the ‘ion diffusion’ (ion inertial Hall) region into the inner current (electron inertial) region from whe...
متن کاملDissipation in turbulent plasma due to reconnection in thin current sheets.
We present in situ measurements in a space plasma showing that thin current sheets the size of an ion inertial length exist and are abundant in strong and intermittent plasma turbulence. Many of these current sheets exhibit the microphysical signatures of reconnection. The spatial scale where intermittency occurs corresponds to the observed structures. The reconnecting current sheets represent ...
