Sharp boundary analysis of electrostatic flute modes
Abstract
A linear, electrostatic, stability analysis of a magnetized crossfield drifting plasma with a sharp boundary is presented. The analysis corrects an error in a previously published sharp boundary theory [Phys. Fluids 19, 882 (1976)] and extends another theory [Geophys. Res. Lett. 14, 60 (1987)] to include finite electron mass and nonneutral perturbations. The instability's long wavelength structure is associated with the classical flute instability, while the peak of the growth rate curve, at much shorter wavelengths, is a Bunemanlike instability.
