Ion acoustic solitary wave in an ion beam driven dusty plasma

Low temperature plasmas containing massive charged dusts have attracted a considerable attention over the last few decades. Such plasmas are relevant in astrophysical settings, such as formation of stars in interstellar clouds or physical processes in cometary tails and planetary magnetospheres as well as in industrial plasmas, e.g., semiconductor processing etc.. The presence of these charged dusts in electron-ion plasmas modifies the propagation of dust ion-acoustic wave (DIAWs) or dust-acoustic wave (DAWs). On the other hand, it is seen that energetic charged particles such as ion beam can significantly modify the propagation characteristics of solitary waves in plasmas. Also, it has been observed that the propagation of high current finite length ion beam in the background plasma plays a significant role in many applications, e.g., heavy-ion fusion, plasma lenses, cosmic ray propagation etc . Here based on plasma fluid theory as well as along with experimental demonstrations, all the different features of ion acoustic solitary waves in an ion beam driven dusty plasma are discussed in detail keeping in view of basic as well as applied plasma physics.
