Description

ECRH was combined with NBI at moderate and high densities with on- and off-axis heating. Density control was achieved for combined heating in long pulse operation despite the beam fueling in contrast to discharges with pure NBI heating. Particle confinement degradation by profile changes inferred by ECRH is discussed as a possible mechanism. The impurity confinement is strongly affected and is discussed for on- and off-axis combined heating conditions
