VG2 CRS D1 Detector Electron Counting Rates During Uranus Encounter

Voyager 2's Cosmic Ray System electron telescope recorded electron kinetic energies above approximately 1 MeV during the Uranus encounter. The D1 detector experienced saturation near a maximum counting rate of approximately 50,000 counts/sec between 1986-01-24T18:10:50Z and 1986-01-24T19:02:02Z. This data set is provided by the National Aeronautics and Space Administration.

Use Cases

• Analyzing electron flux saturation events based on the described saturation period and maximum counting rate
• Correcting counting rates for dead time based on the formula provided in the description
• Studying electron kinetic energy distributions above approximately 1 MeV near Uranus
• Modeling cosmic ray instrument behavior during high-intensity events

Strengths

• Data originates from the Voyager 2 spacecraft's Cosmic Ray System instrument
• Specific saturation event documented with a maximum rate of approximately 50,000 counts/sec and precise time range
• Includes a formula for dead time correction of counting rates

Limitations

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