摘要	In this work, the predicted application of the quasi-snowflake (QSF) magnetic equilibrium on the EAST new designed lower divertor shape is presented and compared with the conventional magnetic configuration by using SOLPS-ITER simulation. The performance of heat flux control, power dissipation of the QSF divertor (QSFD) are studied on the potential EAST new upgrade lower tungsten (W) divertor. The results indicate that QSFD could significantly increase the connection length and flux expansion, thus reduce the heat flux loads to the target significantly. By considering the neon (Ne) impurity seeding, the simulation result shows that the QSFD has higher power dissipation than that of standard divertor (SD), which is caused by the different Ne particle dis-tribution in SD and QSFD.
