Magnetic reconnection is explored on the Terrestrial Reconnection Experiment (TREX) for asymmetric inflow conditions and in a configuration where absolute rate of set by an external drive. pileup enhances upstream magnetic field high density inflow, leading to increased Alfven speed helping lower normalized values expected from theoretical consideration. In addition, shock interface between far supersonic plasma region flux observed, important overall force balance system, hereby...
During magnetic reconnection in collisionless space plasma, the electron fluid decouples from field within narrow current layers, and theoretical models for this process can be distinguished terms of their predicted layer widths. From theory, off-diagonal stress pressure tensor is related to thermal non-circular orbit motion electrons around lines. This becomes significant when width reconnecting approaches small characteristic length scale motion. To aid situ spacecraft numerical...
The rate of reconnection characterizes how quickly flux and mass can move into out the region. In Terrestrial Reconnection EXperiment (TREX), at which antiparallel asymmetric occurs is modulated by presence a shock region pileup in high-density inflow. Simulations utilizing generalized Harris-sheet geometry have tentatively shown agreement with TREX's measured scaling relative to system size, indicative transition from ion-coupled toward electron-only reconnection. Here, we present...
Supermagnetosonic perpendicular flows are magnetically driven by a large radius theta-pinch experiment. Fine spatial resolution and macroscopic coverage allow the full structure of plasma-piston coupling to be resolved in laboratory experiment for first time. A moving ambipolar potential is observed reflect unmagnetized ions twice piston speed. Magnetized electrons balance radial via Hall currents generate signature quadrupolar magnetic fields. Electron heating reflected ion foot adiabatic.
