2D PIC modeling of the helical scrape-off layer current driven by hybrid divertor biased targets in tokamak plasmas
The heat flux control of the divertor plate via strike-point splitting retail-packaged generated by biased targets was proposed in the HL-2A tokamak (Cui et al 2021 Fusion Eng.Des.173 112963).To understand the helical scrape-off layer (SOL) currents driven by hybrid biasing, two SOL current models (model A and B) are employed.Model A is a simplifie
