Abstract

During ICR heating of deuterium plasma, the enhancement of the fusion yield due to second harmonic heating has not been observed to be as large as theoretically expected both on TEXTOR and on JET. This is supposed to be partly due to the unavoidable presence of a small amount of hydrogen which absorbs the wave at its fundamental cyclotron resonance. In the third harmonic heating scenario, this absorption of the wave by the residual hydrogen does not take place. Third harmonic (f = 3f(CD)) ICR heating has therefore been combined with neutral beam (co)injection in a deuterium plasma. The presence of NB injection is necessary to allow the coupling of the RF power to the plasma.
