The heating power set-up shown in figure 1 will allows us to investigate the effect of ECCD with different combinations of power and ECCD efficiency. Studies of coupling between NBI-driven AEs and low frequency zonal flows will benefit from scenario in which AEs activity can be altered without inducing large changes in plasma conditions.
