Experimental studies of magnetic reconnection*
Laboratory magnetic reconnection experiments have been performed for nearly 20 years. Elegant experiments by Stenzel and Gekelman @R. L. Stenzel and W. Gekelman, Phys. Rev. Lett. 42, 1055 ~1979!; W. Gekelman and R. L. Stenzel, Phys. Rev. Lett. 54, 2414 ~1985!# focused on the measurement of field quantities with a single movable probe in a highly reproducible plasma. Observations included a very...
متن کاملNumerical Studies of Weakly Stochastic Magnetic Reconnection
We study the effects of turbulence on magnetic reconnection using three-dimensional numerical simulations. This is the first attempt to test a model of fast magnetic reconnection proposed by Lazarian & Vishniac (1999), which assumes the presence of weak, small-scale magnetic field structure near the current sheet. This affects the rate of reconnection by reducing the transverse scale for reconn...
متن کاملExperimental Study of Current-Driven Turbulence During Magnetic Reconnection
Magnetic reconnection is an important process in magnetized plasmas ranging from the laboratory to astrophysical scales. It enables the release of magnetic energy believed to power solar flares and magnetospheric substorms. Reconnection also controls the evolution of the topology of the magnetic field, enabling deleterious instabilities, such as the sawtooth instability in fusion experiments, t...
متن کاملExperimental observation of correlated magnetic reconnection and Alfvénic ion jets
Correlations between magnetic reconnection and energetic ion flow events have been measured with merging force free spheromaks at the Swarthmore Spheromak Experiment. The reconnection layer is measured with a linear probe array and ion flow is directly measured with a retarding grid energy analyzer. Flow has been measured both in the plane of the reconnection layer and out of the plane. The mos...
متن کاملExperimental study of ion heating and acceleration during magnetic reconnection*
Ion heating and acceleration has been studied in the well-characterized reconnection layer of the Magnetic Reconnection Experiment @M. Yamada et al., Phys. Plasmas 4, 1936 ~1997!#. Ion temperature in the layer rises substantially during null-helicity reconnection in which reconnecting field lines are anti-parallel. The plasma outflow is sub-Alfvénic due to a downstream back pressure. An ion ene...
