英文摘要The edge plasma code package SOLPS5.0 is employed to simulate the divertor power footprint widths of the experimental advanced superconducting tokamak (EAST) L-mode and ELM-free H-mode plasmas. The divertor power footprint widths, which consist of the scrape-off layer (SOL) width lambda(q) and heat spreading S, are important physical parameters for edge plasmas. In this work, a plasma current scan is implemented in the simulation to obtain the dependence of the divertor power footprint width on the plasma current I-p. Strong inverse scaling of the SOL width with I-p has been achieved for both L-mode and H-mode plasmas in the forms of lambda(qLmode)= 4.98 I(p)(-0.68)and lambda(q,H-mode) = 1.86 x I-p(-1.08). H mode p 1.08 Similar trends have also been demonstrated in the study of heat spreading with SL-mode=1.95 x I-q(-0.542) and SH-mode= 0.756 x I-q(-0.872) In addition, studies on divertor peak heat load and the magnetic flux expansion factor show that both of them are proportional to plasma current. The simulation work here can act as a way to explore the power footprint widths of future tokamak fusion devices such as ITER and the China Fusion Engineering Test Reactor (CFETR).
