Long-duration one-dimensional PIC simulations of Buneman-unstable electron and ion distributions are presented, providing detailed phase-space videos of the time-dependence. The dataset was authored by I.H. Hutchinson from the Plasma Science and Fusion Center Dataverse and was last updated on June 2, 2026. Analytical theory of steady nonlinear potential structures is compared with the nonlinear simulations.
Use Cases
- Validate analytical models of nonlinear potential structures based on simulation results.
- Study the formation and evolution of electron holes and coupled hole-solitons based on the described phase-space dynamics.
- Analyze the effect of initial ion temperature relative to electron temperature on ion density modulation.
- Investigate the reflection and persistence of electron holes and coupled hole-solitons in high-available-energy cases.
Strengths
- Includes detailed phase-space videos of the time-dependence of the instability.
- Compares simulation results with analytical theory of steady nonlinear potential structures.
- Last updated on June 2, 2026, indicating recent maintenance.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The description focuses on physics results; the exact data format and structure are unspecified.
