Drift-Alfven Instability in the Presence of Sheared Flows
Abstract
In the present report the temporal evolution of the drift-Alfven instability in a sheared plasma flow is considered. The analysis is based on a system of four equations for the perturbed electrostatic and magnetic potentials and for the electron and ion pressure perturbations. The temporal evolution of the spatial Fourier modes of the perturbations is studied directly without the use of spectral expansions in time. The results provide a novel view into the dynamics of the drift-Alfven instability in plasmas with shear flow.
