Zusammenfassung |
We study the collisionless dynamics of electrons in the shock ramp
using the numerical trajectory analysis in the model electric and magnetic fields of the
shock. Even with very modest assumptions about the cross-shock potential the electron
trajectories are very sensitive to the width of the ramp. The character of electron motion
changes from the fully adiabatic (with conservation of v2<perp>
/B) when the ramp is wide, to the
nonadiabatic one, when the ramp becomes sufficiently narrow. The downstream electron
distribution also changes drastically, although this change depends on the initial
electron temperature. |
