A model of the bifurcated current sheet: 2. Flapping motions
[1] A generalization of the Harris [1962] model has recently been proposed to explain the multi-spacecraft Cluster observations of thin bifurcated current sheets. It utilizes features of the ion motion in thin sheets and assumes anisotropy of the ion species. We report the results of 2D PIC simulations based on this model. Simulations confirm its self-consistency. They also reveal the lower-hyb...
متن کاملA Current Disruption Mechanism in the Neutral Sheet: a Possible Trigger for Substorm Expansions
A linear analysis is performed to investigate he kinetic ross-field streaming instability in the Earth's magnetotail neutral sheet region. Numerical solution of the dispersion equation shows that the instability can occur under conditions expected for the neutral sheet just prior to the onset of substorm expansion. The excited waves are obliquely propagating whistlers with a mixed polarization ...
متن کاملCurrent sheet flapping motion and structure observed by Cluster
[1] Fast vertical flapping oscillations of the plasma sheet have been observed by Cluster on September 26, 2001. The flapping motion had vertical speeds exceeding 100 km/s, an amplitude in excess of 1 RE and a quasiperiod of 3 min. The current sheet was mostly tilted in the Y-Z plane (with the tilt sometimes exceeding 45 ). The waves had the properties of a kink mode and propagated toward the d...
متن کاملA Generalized Modular Multilevel Current Source Inverter
This paper proposes a novel topology of multilevel current source inverter which is suitable to apply in low/medium voltage. The proposed topology is capable of producing desirable bidirectional output current levels. Furthermore, it can employ symmetrical DC current sources as well as asymmetrical ones which is a significant advantage. Asymmetrical mode makes it possible to generate a great nu...
متن کاملDouble discontinuities at the magnetotail plasma sheet-lobe boundary
A double discontinuity is a compound structure composed of a slow shock layer and an adjoining rotational discontinuity layer on the postshock side. We use highresolution data from Geotail and Wind spacecraft to examine the interior structure within the finite thickness of the discontinuity at the plasma sheet-lobe boundary and found that recognizable MHD structures at the boundary can be stand...
