Experimental 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...
متن کاملExperimental 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 کاملObservation of ion acceleration and heating during collisionless magnetic reconnection in a laboratory plasma.
The ion dynamics in a collisionless magnetic reconnection layer are studied in a laboratory plasma. The measured in-plane plasma potential profile, which is established by electrons accelerated around the electron diffusion region, shows a saddle-shaped structure that is wider and deeper towards the outflow direction. This potential structure ballistically accelerates ions near the separatrices...
متن کاملFast Magnetic Reconnection via Jets and Current Microsheets
Numerical simulations of highly nonlinear magnetic reconnection provide evidence of ultrathin current microsheets. These small-scale sheets are formed by strong exhaust jets from a primary large-scale current layer. The overall size of the secondary microsheet is determined by the thickness of the primary sheet. Preliminary scalings show that the thickness of the microsheet varies linearly with...
