Abstract

The Kelvin-Helmholtz mode instability driven by an equilibrium radialelectric field in a cold plasma is studied analytically for flute-typeperturbation in cylindrical geometry. The growth rate and a thresholdin the radial gradient scale length of the E× B drift frequencyfor instability are obtained.
