摘要：
In this paper, several effects observed in the ion-acoustic instability induced by a negative dusty particle barrier, are described. We derive the dispersion relation in a one dimensional ion-beam plasma system using our fluid-kinetic-algebraic treatment taking into account forces due to the large negative charge of the dust particles in a stationary regime. That means that fluctuations of charge of dust particles are neglected. Considering a simple model where dust particles can be considered as immobile and the presence of collisions is taken into account, we calculate modes and instabilities to analyze this new effect.
