High fusion triple product has been obtained in the advanced scenarios with high normalized beta (βN) on the Experimental Advanced Superconducting Tokamak (EAST).A record value of ni0Ti0τE1.0?×?1019m-3ke V s for EAST deuterium plasma has been achieved,which is due to the formation of strong and broad internal transport barriers (ITBs) in ne,Teand Tiprofiles.Analysis shows that the strong ITB formation could be attributed to the reduction of transport from ITG modes.Based on the analysis,the physical mechanisms and methods to furtherimprove the plasma performance are discussed.
