Two-point model analysis of SOL plasma in EAST

A two-point model is used to investigate the characteristics of scrape-off layer(SOL) plasma with the field line tracing method in the experimental advanced superconducting tokamak. The profiles of plasma density, temperature and particle flux on the divertor target calculated by the model are in reasonable agreement with experimental observation. Moreover, the profiles of plasma parameters on the divertor target strongly depend on the SOL magnetic topology or the equilibrium configuration from the modeling.
