| Zusammenfassung |
| The nonlinear dustgrain-charging and the influence of the
ion density and temperature on electrostatic waves in a dusty plasma having trapped ions
are investigated by numerical calculation. This work is the first approach to the effect
of trapped ions in dusty plasmas. The nonlinear variation of the dust-charge is examined,
and it is shown that the characteristics of the dustcharge number sensitively depend on
the plasma potential, Mach number, dust mass-to-charge ratio, trapped ion density and
temperature. The fast and slow wave modes are shown in this system. An increase of the ion
temperature decreases the dust-charging rate and the propagation speed of ion waves. It is
found that the existence of electrostatic ion waves sensitively depends on the ion to
electron density ratio. New findings of the variable-charge dust grain particles, ion
density and temperature in a dusty plasma with trapped ions are predicted. |
