Abstract

Landau damping of ion-acoustic waves is theoretically studied in a dope plasma of a light inert gas like helium in the presence of plasma of a heavy inert gas like argon, considering both fluid model and kinetic model. Damping rates of the ion-acoustic waves in dope plasma are different for the two models which may be experimentally investigated by imposing some conditions. Other cases of Landau damping in Vlasov plasma are also considered. The study is intended to be in support of the experimental investigation of Landau damping free from the influence of other non-collisional as well as collisional damping.

Keywords
