Abstract

A uniform compressible plasma with a uniform flow along the magnetic field in the presence of a resistive wall is shown to be subject to tow instabilities. For the first instability, the flow velocity is required to exceed the Alfven speed whereas for the second it need only exceed the sound speed. For a sufficiently high ion temperature, ion Landau damping is shown to stabilize the second instability associated with the sound speed.
