摘要：
dImpurity ion temperatures and parallel flow velocities in the DIII-D divertor have been measured from the shapes and shifts of visible spectral lines of C II, C III, and B II. Spectral multiplet patterns are analyzed by fitting them to theoretical profiles that incorporate exact calculations for the Zeeman/Paschen-Back effect.. Both normal flows toward the target plate and reversed hows away from the target plate are observed in the outer divertor leg; only flows toward the plate are detected in the inner leg.
