Trapped Radiation and High-Energy Protons

NSSDCA ID: 1964-054A-19

Mission Name: OGO 1
Principal Investigator:Prof. James A. Van Allen


This experiment was designed to detect charged particles and measure omnidirectional intensities of outer belt electrons in order to understand the origin of the belts and the fluctuations in the belts. A detector composed of GM tubes and solid-state junction devices was capable of measuring electrons of energies greater than 40, 150, and 1600 keV and protons of energies greater than 0.5, 3.5, and 16 MeV. More details regarding experiment design may be found in Van Allen, J. A., and G. Crossett, Jr., ed., "Instrument report for a trapped radiation experiment for EGO (S-49)(OGO-1)," State Univ. of Iowa, Iowa City, January 29, 1963 (TRF B13005).
