Abstract
The theory of drift waves in a sheared slab geometry in the presence of dust is analyzed. It is shown that the well-known stability of the drift wave in a sheared slab geometry does not hold in the presence of dust particles in the plasma. It is observed that in the presence of dust, the magnetic shear damping is reduced drastically and both collisionless and collisional drift waves become unstable for typical parameter regimes of tokamak operation. It is suggested to consider drift waves as an underlying dynamics of anomalous transport in tokamak edges.
