A Gas Puff Imaging diagnostic on the TCV tokamak provides two-dimensional insights into Scrape-Off-Layer turbulence dynamics. The dataset, authored by researchers including Wüthrich, C. and Theiler, C., likely contains measurements of filament shape, velocity, and density profiles from L-mode, attached, lower single-null discharges. It was last updated on 2026-05-14.
Use Cases
- Analyze filament shape and elongation based on 2D imaging data mentioned in the description
- Compare radial and poloidal filament velocities in different SOL regions
- Study the connection between upstream and divertor-localized filaments using field-line tracing consistency
- Assess the impact of divertor-localized filaments on electron density profile broadening using filament statistics
Strengths
- Data originates from a new Gas Puff Imaging diagnostic providing 2D insights
- Study includes specific quantitative observations, such as filament diameters of ~15 sound Larmour radii and radial velocities of ~400 m/s
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Description metadata is limited; actual data quality requires manual inspection after download
