Abstract

We have developed a self-consistent integrated simulation model of core and scrape-off-layer (SOL)/divertor transport. This model enables the user to investigate operational scenarios with compatible high-confinement core plasmas and detached divertor plasmas. A 1.5D core code TOPICS-IB and a 2D divertor code SONIC are successfully coupled using a Multiple Program Multiple Data parallel computing system. This integrated code, which can include Monte-Carlo models for neutrals and impurities, provides efficient plasma/neutral simulations. The dynamic simulation for the L/H transition in JT-60SA is carried out by this integrated code using a current-diffusive ballooning mode (CDBM) transport model that includes the E×B shearing effect. The impact of SOL/divertor transport on the L/H transition is studied.
