Abstract
The STRAHL transport code has been implemented on DIII-D to calculate tungsten (W) density profiles from spectrometer, soft x-ray, and bolometer measurements during a metal rings campaign. STRAHL results show that the ratio of the convective velocity to particle diffusion peaks near ρ ∼ 0.3 leading to a high W concentration near the magnetic axis.
