Voyager 2 LECP: Charged Particle Flux Measurements at Uranus

Electron and ion counting rate and flux data from the Low Energy Charged Particle experiment on Voyager 2 during its Uranus encounter. The dataset includes a subset of nearly 100 LECP channels measuring particles above 13 keV for electrons and 24 keV for ions. Data were collected by NASA at 6.4-minute intervals during the far encounter phase.

Use Cases

• Analyzing charged particle anisotropy based on the rotating head and eight angular sectors described.
• Studying particle species composition (electrons, protons, alpha particles, nuclei) using the channel subset.
• Investigating background contamination levels using Sector 8 rates shielded by aluminum.
• Converting raw rate data to physical intensity units using the documented geometric factors and energy bandpasses.

Strengths

• Includes nearly 100 distinct measurement channels for detailed particle analysis.
• Provides globally calibrated data with documented calibration procedures using Sector 8.
• Offers high temporal resolution with 6.4-minute measurements during the encounter.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Raw 'Rate' data requires conversion to intensity, dependent on uncertain determinations like mass species.
