Simulations spanning 2 orders of magnitude in resistivity analyze poloidal asymmetries in electron density in a COMPASS-sized, diverted tokamak. The dataset was created by Raúl Gerrú, Matthias Wiesenberger, Theresa M Wilks, and Laszlo Horvath and was last updated on 2026-06-02. It uses the 3D full-F, isothermal, electromagnetic gyro-fluid model FELTOR to study the edge and scrape-off layer.
Use Cases
- Validate gyro-fluid models against experimental observations based on simulated density asymmetries.
- Study the impact of plasma resistivity on transport in the scrape-off layer based on the described resistivity parameter sweep.
- Analyze poloidal density profiles relative to the outer midplane in diverted tokamak configurations as described in the study.
- Investigate discrepancies between simulation and experiment for high-density plasmas in the SOL as noted in the description.
Strengths
- Simulations cover a defined parameter range, spanning 2 orders of magnitude in resistivity.
- Analysis quantifies specific asymmetry percentages, such as up to 55% relative density asymmetry in the SOL.
- Model is specified as a 3D full-F, isothermal, electromagnetic gyro-fluid model (FELTOR) for a COMPASS-sized tokamak.
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.
