Prediction of the kinetic profiles in H-mode plasma discharges on EAST using core-pedestal coupling

The physical processes in tokamak plasma are strongly related to the coupling between the core and the pedestal. The accurate prediction of the kinetic profiles (electron temperature and density) from the pedestal to the core lays the physics basis for fusion performance optimization in future plasma-burning tokamak devices. Based on the optimized width model ([Formula: see text] between the pedestal width [Formula: see text] and the square root of the poloidal pedestal beta [Formula: see text]) from empirical observations in type-I edge-localized mode (ELM) H-mode discharges, the REPED model is further used to predict the pedestal structures for type-III ELM H-modes on EAST in this work. By combining the REPED model and the TGYRO transport module, the core-pedestal coupling was initially employed for predicting the kinetic profiles ranging from the axis to the separatrix in H-mode plasma discharges on EAST.
