99 Probes: Surface Currents from Cylindrical Langmuir Probe PIC Simulations

Surface currents on cylindrical Langmuir probes from Particle-in-Cell (PIC) simulations supporting the paper 'Finite-Length Effects on Cylindrical Langmuir Probes'. The dataset includes VTK files for individual simulations and a coefficients.csv file with fitting coefficients for all runs. Sigvald Marholm from the University of Oslo created this data.

Use Cases

• Validate PIC simulation results for Langmuir probes based on provided surface current data.
• Analyze the relationship between probe length and current collection using the encoded simulation parameters.
• Apply fitting coefficients to model probe current-voltage characteristics as described in the associated paper.
• Study finite-length effects on cylindrical probe performance across different plasma densities and temperatures.

Strengths

• Data is directly linked to a specific, peer-reviewed research paper, providing clear context.
• Simulation parameters like density, temperature, voltage, and probe length are systematically encoded in folder names.
• Includes both raw simulation output (VTK files) and derived analytical fitting coefficients in a separate CSV file.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
