Two-dimensional fluid simulations of the ITER SOL plasma

Abstract

Simulations of scrape-off layer plasmas in ITER have been performed using a 2-d fluid model with a set of perpendicular energy and particle transport coefficients matching those determined in a limited number of experiments on presently operating tokamaks. These simulations include single- and double-null magnetic configurations, and ignited and driven operation. Predictions are made of divertor power loading, density scrape-off length, effective core/edge recycling coefficient, and divertor sheath electron temperature.
