Current 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 کاملParticle Acceleration in a Folded Current Sheet
Two-dimensional particle simulations of a relativistic Harris current sheet of pair (e ±) plasmas have demonstrated that the system is unstable to the rela-tivistic drift kink instability and that a new kind of acceleration process takes place in the deformed current sheet. This process contributes to the generation of non-thermal particles and contributes to the fast magnetic dissipation in th...
متن کاملCorrelation between energetic ion enhancements and heliospheric current sheet crossings in the outer heliosphere
[1] Voyagers 1 and 2 observed highly-variable beams of energetic ions in the foreshock region upstream of the termination shock (TS). At Voyager 2 (V2), the ion intensities are generally not related to the plasma properties. At Voyager 1 (V1), the beams are often coincident with crossings of the heliospheric current sheet (HCS). The V1 intensity peaks occur when the HCS is crossed from negative...
متن کاملA Review of Polarized Ion Sources
There have been significant advancements in the capabilities of polarized ion sources in the four years following the last review given to the Particle Accelerator Conference in 1991[1]. Polarized nuclei are an important nuclear physics probe and present day experiments require that the polarized ion source provide beams with high polarization, high beam current, exceptional beam quality and lo...
متن کاملA model of the bifurcated current sheet
[1] Recent Geotail and Cluster observations revealed that thin current sheets in the near-Earth tail may have a bifurcated structure. In some cases the electrons are found to dominate the current. We present a generalization of the Harris current sheet equilibrium, which reproduces these features. The model ion distribution contains an additional element, viz. the quasi-adiabatic invariant of t...
