Turbulent Fluctuations During Pellet Injection into a Dipole Confined Plasma Torus

HDF5 and CSV datafiles accompany a Physics of Plasmas article on turbulent fluctuations in a plasma torus. The dataset includes time-series measurements from a four-channel microwave interferometer, a 16-channel photodiode array, and ECRH heating power, sampled at microsecond intervals. Data from Columbia University researchers corresponds to figures in the paper, covering a specific 2-second experimental time window.

Use Cases

• Analyzing plasma density fluctuations based on four-channel microwave interferometer data.
• Studying turbulent coherence and spectral properties based on derived CSV files for line density and photodiode signals.
• Correlating injected heating power with plasma behavior based on ECRH power time-series data.
• Investigating spatial structure of turbulence based on multi-channel photodiode array measurements.

Strengths

• Data is directly linked to a peer-reviewed article in Physics of Plasmas, providing context and validation.
• Includes high-temporal-resolution measurements with sample periods as low as 8 microseconds.
• Covers multiple synchronized diagnostic channels (interferometer, photodiode array, heating power) for a 2-second experimental period.

Limitations

• Column-level documentation is absent; field semantics must be inferred from the paper or file inspection.
• Row count is unknown for the overall dataset, which may limit suitability assessment for large-scale ML.
• Last update date is unknown; freshness unverified.
