VG2 JUP CRS: Voyager 2 Cosmic Ray Particle Flux Data at Jupiter

Cosmic ray particle flux data derived from the Voyager 2 spacecraft's Cosmic Ray Subsystem (CRS) during its Jupiter encounter. The CRS includes two High Energy Telescopes, four Low Energy Telescopes, and an Electron Telescope, with detectors designed for large geometric factors and low power consumption. Data collection methods were adapted for high-flux environments within the Jovian magnetosphere, where guard counters were turned off to prevent blocking desired counts.

Use Cases

• Modeling Jovian magnetosphere dynamics based on high particle flux measurements.
• Analyzing cosmic ray spectra based on derived proton, ion, and electron flux data.
• Studying instrument performance in high-radiation environments based on the described detector adaptations.
• Comparing interplanetary and planetary particle environments based on the described anticoincidence guard counter procedures.

Strengths

• Data originates from the NASA Voyager 2 mission, a primary source for outer solar system science.
• Instrumentation includes multiple telescope types (HET, LET, TET) with large geometric factors (~0.48 to 8 cm^2 ster).
• Description details specific adaptations for high-flux conditions at Jupiter, indicating context-aware data collection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
