Abstract

The linear dispersion of the ion temperature gradient (ITG) modes, in the presence of a non uniform background ion velocity U∥ = U ∥(x) ez, in the direction of the sheared equilibrium magnetic field B0 = B0(x) ez, has been studied in the frame of the two-fluid guiding center approximation, in slab geometry. Generally speaking, the presence of an ion flow destabilizes the oscillations. The role of the excited K-H instability is discussed. © 2006 American Institute of Physics.
