Abstract:
Numerical analysis on Scrape-Off Layer (SOL) Plasma and divertor plasma in tokamaks is made by using two-dimensional time-dependent transport code (UEDA code). Plasma transport in SOL and the divertor region is calculated for given particle and heat sources from the main plasma. Scaling study of the density, the temperature and their fall-off lengths is done for JFT-2M tokamak. The results show us inter-relations between the divertor plasma parameters and the core plasma confinement. The operational conditions of the core to guarantee the divertor performance are discussed.
