Solar Wind Experiment

NSSDCA ID: 1967-040A-04

Mission Name: Vela 4A
Principal Investigator:Dr. Samuel J. Bame


Four thin window Geiger-Mueller counters and one electrostatic analyzer - electron multiplier were used to study the solar wind and low energy electrons in interplanetary space and the magnetotail. The Geiger-Mueller counters measured the flux and angular distribution of electrons greater than 45 KeV. This experiment was active as of January 15, 1970. The electrostatic analyzer-electron multiplier unit was not working.
