Hisaki Telescope MCP Dark Count Rates and Space Weather Correlations

Dark count rates were measured by the micro-channel plate detector on the Hisaki space telescope from 2013 to 2018. The dataset is used to analyze transient radiation enhancement events in low Earth orbit, linking them to space weather parameters. It was created by Ryoichi Koga and published in 2026.

Use Cases

• Predict MCP dark count rate enhancements using GOES X-ray, proton, and electron measurements.
• Identify precursor signals for radiation belt variations by analyzing time-lagged SYM-H index and orbital parameters.
• Apply SHAP analysis to interpret the contribution of non-delayed X-ray variations to detector response events.
• Model the correlation between coronal mass ejection indicators and factor 2-5 amplitude increases in dark counts.

Strengths

• Data spans a 5-year period from 2013 to 2018.
• Analysis combines multiple data sources: Hisaki MCP counts, GOES measurements, and SYM-H index.
• Uses a two-stage regression analysis with model training on 2013-2016 data.

Limitations

• Dataset is small, described within a single 423.8 KB PDF file.
• Raw observational data and specific column structures are not directly provided.
• Analysis focuses on specific enhancement events in 2017 and 2018, limiting general temporal scope.
