ICI-4 E-N Collisional Current Simulations

Particle-in-cell simulation data for Langmuir probe currents under electron-neutral collisions in the lower E-region ionosphere. Steffen M. Brask from the University of Oslo created this dataset to accompany a research paper on collision effects. Each simulation file contains probe current, particle energies, and electric potential data sampled at 2 GHz.

Use Cases

• Modeling electron saturation current to a Langmuir probe based on simulated probe bias and collision frequency.
• Analyzing the evolution of kinetic and potential energy within a simulated plasma domain based on the described energy groups.
• Studying the effects of electron-neutral collision frequency on ion and electron currents based on the parameterized simulation folders.

Strengths

• Data is sampled at a high frequency of 2*10^9 Hz, providing fine temporal resolution.
• Specific plasma parameters are provided, including density (9.597e10 m−3) and temperatures (Te=441K, Ti=475K).
• Simulations cover a controlled parameter space, including collision frequency powers and probe bias voltages.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred from the hierarchical HDF5 structure description.
• Last update date is unknown; freshness unverified.
