Vega 1 Plasma Energy Analyzer Observations of Comet Halley

Status: ARCHIVED

Abstract: The PLASMAG-1 instument package included six different sensors: A0 plasma impact detector for measuring neutral particle flux, (manufactured by R. Grard, ESA/ESTEC, Noordwijk, The Netherlands) A1 Faraday cup for measuring integral ion flux from solar direction, A2 Faraday cup for measuring integral ion flux and neutral particles from ram direction, A3 spherical electrostatic analyzer for measuring ions from ram direction in the energy range of 15 eV - 3.6 keV in 120 logarithmically spaced channels, A4 spherical electrostatic analyzer for measuring ions from solar direction in the energy range of 60 eV - 30 keV in 60 logarithmically spaced channels, A5 cylindrical electrostatic analyzer for measuring ions perpendicular to the ecliptic plane in the energy range of 2 eV - 10 keV in 30 logarithmically spaced channels.
