CFETR equilibrium with self-consistent pedestal structure

Abstract The Chinese Fusion Engineering Test Reactor (CFETR), which aims to fill the gaps between the International Thermonuclear Experimental Reactor (ITER) and DEMO, is in the design stages. Plasma equilibrium is an important basis for tokamak plasma research. We present a method for constructing CFETR equilibria with a self-consistent pedestal structure, using an EPED-like model and the Sauter bootstrap current model. With this method, the pedestal structures of the snowflake (SF) divertor configuration for CFETR are calculated as well. It is shown that the pedestal heights and widths of SF+ and SF- are slightly larger than those in the standard divertor configuration.
