Abstract

In this work, we have obtained the dispersion relation for the space-charge wave propagating in a dusty plasma
column containing collisional streaming ions by using the fluid equations and the Poisson equation which lead
to a Bessel equation. The growth rate of the space-charge and the geometric and collisional effects on the
growth rate have been investigated. It is shown that the space-charge wave can be excited for a large axial wave
number. The growth rate of excitation increases as the order of the roots of the Bessel function increases. It is
also found that the growth rate decreases with an increase of the radius of column as well as with an increase of
the collision frequency. In addition, it is found that the disturbance of wave can be damped only for small wave
numbers and the ion collision plays a significant role in the physical properties of the space-charge wave.
