Langmuir probe measurements in DIII-D tokamak Wide Pedestal QH-mode plasmas show target electron temperatures up to ~150eV. The dataset contains results from SOLPS-ITER modeling, including carbon density (C6+) and C2+ density, used to match experimental radial profiles. It was authored by X. Ma et al. from the Plasma Science and Fusion Center and last updated on 2026-06-26.
Use Cases
- Validate SOLPS-ITER simulation outputs against experimental Langmuir probe and spectroscopic measurements.
- Study the effect of particle drifts (B×∇B, E×B) on carbon impurity distribution in double-null and single-null configurations.
- Analyze the relationship between high sheath temperature, carbon self-sputtering, and impurity sourcing.
- Compare impurity transport behavior between simulations with ion B×∇B drift towards and away from the X-point.
Strengths
- Includes experimental measurements with target electron temperature up to ~150eV.
- Modeling results match measured carbon densities just inside the separatrix, as described.
- Simulations explore specific configurations, such as double-null with full drifts and single-null with reversed toroidal field.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The description is highly technical, requiring domain expertise for interpretation.
