Hall Thruster Plasma Oscillation Data from Three Simulation Cases

18 MATLAB data files contain outputs from Higher Order Dynamic Mode Decomposition (HODMD) analysis of Hall thruster plasma simulations. The data, produced by researchers from UC3M in 2022, includes frequencies, growth rates, and amplitudes for variables like plasma density and electric field across nominal, low-voltage, and high mass-flow rate cases. The original simulations were generated using the HYPHEN 2D hybrid PIC/fluid code.

Use Cases

• Identifying dominant oscillation modes in Hall thrusters based on the provided frequencies and growth rates.
• Comparing plasma behavior across different operational regimes (nominal, low voltage, high mass flow) using the three case groups.
• Validating simulation codes against the HODMD-derived modal decompositions of density, temperature, and potential.
• Studying the relationship between ionization production and electric field oscillations using the available variables for the first case.

Strengths

• Includes data for three distinct operational cases (nominal, low voltage, high mass flow), enabling comparative analysis.
• Provides multiple key plasma variables, including density, temperature, potential, and current density.
• Data is associated with a specific Digital Object Identifier (DOI: 10.5281/zenodo.6359505) for stable citation.

Limitations

• Column-level documentation is absent; field semantics must be inferred from the description after download.
• Row count is unknown, which may limit suitability assessment for large-scale machine learning.
• Data may reflect bias inherent to the specific simulation code (HYPHEN) and configurations used.
