2.2.6 spase://CDPP/Instrument/AMDA/Voyager2/PLS PLS Plasma Spectrometer 2009-05-20T21:10:14Z The plasma investigation made use of two Faraday-cup detectors, one pointed along the earth-spacecraft line and one at right angles to this line. The earth-pointing detector determined the macroscopic properties of the plasma ions, obtaining accurate values of their velocity, density, and pressure. Three sequential energy scans were employed with (delta E)/E equal to 29, 7.2, and 1.8%, allowing a coverage from subsonic to highly supersonic flow. The side-looking Faraday cup measured electrons in the energy range from 5 eV to 1 keV. spase://SMWG/Person/John.D.Richardson PrincipalInvestigator NSSDC's Master Catalog http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1977-076A&ex=6 Information about the Plasma Spectrometer (PLS) experiment on the Voyager 2 mission.
