Plasma Probe, Faraday Cup

NSSDCA ID: 1964-054A-14

Mission Name: OGO 1
Principal Investigator:Prof. Herbert S. Bridge


Two multi-grid Faraday cups were used to study the directional intensity of positive ions and electrons of the solar wind, magnetosheath, and magnetotail. One single collector Faraday cup was used to study electrons in four energy windows between 125 eV and 2 keV. Currents in all four energy windows were measured every 9.2 s. One split-collector Faraday cup was to be used to study positive ions, but due to the unexpected spin-up of the satellite, the data collected were useless and no longer exist.
