Abstract

The behaviour of the crossfield current-driven ion-acoustic instability in the presence of a sheared magnetic field and a density gradient is investigated theoretically in the limit in which growth due to inverse Landau damping is small. The shear damping rate is found and the critical shear length shown to vary as (mi/me)⅓ and as ((VD–CS)/CS)–⅔.
