✦ Synopsis

The manifestations of the induced scattering eNects in the generation process of current driven by lower-hybrid (LH) waves are studied taking into account the radiative-resonant interactions. The influence extent of the LH wave modulational instability on current drive is estimated. It is shown that the induced scattering of LH waves on plasma particles leads to a change of the LH waves spectrum and through this leads to an essential influence on fast electrons generation rate and the steady-state current drive. The rnodulational instability of LH waves can provide a "spectral gap" filling in the case of sufficiently strong LH wave pumping.
