Edge plasma parameters influence plasma performance in many different ways (profile stiffness is probably one of the best known examples). In the ELMy H-mode plasma, a thin region with improved transport characteristics (the edge transport barrier) links the core and the scrape-off layer. There is a strong coupling between these three areas, so that even a modest variation of plasma parameters in one region can lead to a dramatic change in the overall plasma performance. A systematic MHD stability analysis and self-consistent integrated predictive modeling of a series of JET ELMy H-mode plasmas, including scans in gas fueling and triangularity, are presented. The main conclusion is that plasma performance indeed sensitively depends on the edge plasma parameters, which should be modeled in a self-consistent way. [ABSTRACT FROM AUTHOR]
