Abstract

The nonlinear coupling between collisional drift waves and a lower-hybrid pump is studied in a cylindrical geometry. A dispersion relation for the collisional drift wave is derived incorporating both ponderomotive and Ohmic-heating effects. It is found that Ohmic heating of electrons enhances the frequency as well as the growth rate of the drift waves. Effects due to the ponderomotive force are insignificant.
