| Zusammenfassung |
| Study of particle dynamics in the Earth’s magnetotail has shown that nonadiabatical ion
acceleration in the neutral sheet may lead to the formation of the non-maxwellian ion
distribution functions. The unique feature of such distribution is the space hole centered on
90° pitch angle so the distribution is not symmetrical about magnetic field direction. Ion
distributions with an empty region in velocity space represent a source of free energy for
excitation as plasma waves as electromagnetic waves.
It was shown that such distributions are really unstable to the electromagnetic waves
generation and the investigation of stability properties of such ion distribution in the relation
to electromagnetic waves was done. |
