Abstract
With the C-wall sustained high performance (with H98y > 1.2 for > 5s) has been achieved in the hybrid regime and is compatible with core n = 1 activity. With the ILW sustained high performance is not achieved and confinement degradation is coincident with core n = 1 MHD (but causality between the MHD and confinement degradation has yet to be established). Due to their effects in causing tungsten impurity accumulation n = 2 and 3 NTMs have a much more significant effect with the ILW than with the C-Wall. This work was carried out within the framework of the EFDA. This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement number 633053 and from the RCUK Energy Programme [grant number EP/I501045].
