Title: Heating and current drive by mode-converted ion-Bernstein waves

Abstract

Previous theoretical analysis has shown that mode-converted ion-Bernstein waves generated at the ion-ion hybrid resonance in an ICRF heated plasma damp effectively on electrons. Recent experiments in tokamaks observe substantial electron heating which is attributed to these ion-Bernstein waves. In this paper, some of the latest theoretical developments on mode conversion, propagation, and damping of ion-Bernstein in tokamaks are presented. The eventual purpose of these studies is to determine the role of ion-Bernstein waves in advanced tokamak scenarios. {copyright} {ital 1996 American Institute of Physics.}
