| Zusammenfassung |
| Current density profiles of 22 thin current sheets, crossed by four Cluster
spacecraft in the magnetotail are compared with the self-consistent model of
anisotropic 1-D equilibrium, including several species of quasi-adiabatic
(transient) ions and drifting electrons. In order to examine ion-scale
features of the current density profile Cluster data from the 2001 and 2004
tail seasons were used when the spacecraft separation was about 2000 and
1000 km, respectively, while electron-scale features are studied using
Cluster data from the 2003 season , when the spacecraft separation was about
200 km. The model ion and electron current density peaks embedded in a
background plasma sheet successfully reproduce observed profiles. Stability
criteria of the model current sheet are also consistent with the experiment. |
