Abstract
Suppression of drift waves by the application of externally launched l ower hybrid waves has been observed experimentally in an ion-beam plas ma system. Suppression is due to ponderomotive force which upshifts th e frequency of the drift wave, thus enhancing the Landau damping of el ectrons. A nonlocal theory incorporating the effect of the finite mode structure is given to explain these experimental results.
