Abstract
The stability of ion-drift-wave eigenmodes in a slab geometry with a sheared magnetic field is investigated. It is found that in contrast to the case of universal and dissipative electron-drift-wave eigenmodes, unstable impurity-driven normal modes can appear if specific conditions are satisfied. In addition, the influence of impurities on unstable ion-temperature-gradient- driven drift eigenmodes is also studied. It is found that, if their density profile is inwardly peaked, the impurities can exert a strong stabilizing influence on these modes.
