Electrostatic Plasma Analysis (Protons .1-18 keV)

NSSDCA ID: 1964-054A-13

Mission Name: OGO 1
Principal Investigator:Dr. John H. Wolfe


This experiment was designed to study the positive ion component of the solar wind plasma. Three quadrispherical electrostatic analyzers, two looking into the orbital plane and one solar oriented, were to be used to detect protons in 30 steps in the range 100 to 18,000 eV. Owing to the unintended spacecraft spin, little useful data were obtained. The sensors could serve as a detector for the magnetopause and bow shock, however. More details regarding experiment design may be found in Beck, C. W., II, et al., "Solar wind measurement techniques. Part 2: solar plasma energy spectrometers," Proceedings of 17th National Aerospace Electronics Conference, Dayton, Ohio, pp. 82-94, May 10-12, 1965 (TRF B01227-000B). Data from this investigation no longer exist.
