Abstract
Dissipative-drift wave instability has been studied in the presence of impurity radiation. A two-fluid model is employed to derive the relev ant equations. A general local dispersion relation is derived. The lat ter is analysed analytically as well as numerically. It is found that drift waves are further destabilized in the presence of impurity radia tion loss. Non-thermal fluctuations are shown to cause both cross-fiel d particle and electron energy transports. The present results can hav e relevance to tokamak edge plasma turbulence.
