“…In the SOL-divertor region, a general fluid description of plasma with one ion-species includes 2-D models such as B2-EIRINE [1,2,18] , the 1-D model [19] and twopoint model [3−5] . Since its results agree fairly well with the results of experiments and complicated numerical simulations, and in view of its clear physical concept and simple mathematic form, the Two-point model has been used widely to explain the results of the SOLdivertor experiments [20] and to survey the parameters for the operational region of the SOL-Divertor plasma for ITER and other reactor designs [3][4][5]21] .…”

An experimental advanced superconducting tokamak (EAST) operation window with the lower hybrid current drive (LHCD) in H-mode is estimated by using a core-SOL-divertor (C-S-D) model validated by the present EAST divertor experiments. The operation window consists of four limits including two usual limits, one of which is the maximum allowable heat load onto the divertor plate, and two additional limits associated with the LHCD. The predictive EAST operation window is not qualified to fulfill its mission for high input power. To extend the operation window, gas puffing and impurity seeding are presented as two effective methods. In addition, the effect of the LHCD current on the operation window is also discussed. Our numerical analysis results provide a reference for the safe operation of EAST experiments with LHCD in future.
