Abstract

Pellet injection into DIII-D plasmas has demonstrated deeper fueling from inner wall ports than from vertical or outside midplane locations, even at much lower pellet speeds. The difference in fuel deposition has been successfully modeled by taking into account ?B and curvature drifts. When using this model for ITER we have achieved fuel deposition well beyond the scrape off layer for inner wall injected pellets and this scheme promises to provide sufficient fueling for operating ITER at high density. ELMs triggered from small outer wall (low field side) injected pellets may prove to be a useful means to limit the ELM magnitude.
