Abstract
The temporal evolution of the dust grain charge is investigated for the first
time in a dusty plasma with an ion beam. The grain charge attains to the
stationary state after the fluctuation of short time. The dust charge
increases as the ion beam temperature and the plasma ion density increase, but
decreases as the beam density increases. The speed of the wave increases as
the ion density and temperature increase, whereas it decreases as the dust
charge increases. The variable dust mass-to-charge and ion-to-electron density
ratios govern the existence of dust acoustic waves. The findings of this
investigation may be useful in understanding laboratory plasma phenomena.
