Title: Effects of Inhomogeneities in Plasma Density on the Beam-Plasma Instability and Landau Damping
Abstract: A numerical computer simulation using a charge sheet model is employed to investigate the beam-plasma instability and Landau damping in a one-dimensional, finite-length, inhomogeneous plasma. The results confirm the theoretical predictions that the inhomogeneities in plasma density distribution reduce the spatial growth rate of the beam-plasma instability and increase the Landau damping rate.
