NSSDCA ID: 1961-020A-04
Mission Name: Explorer 12The instrumentation for the Cosmic-Ray Experiment consisted of (1) a double scintillation counter that measured 55- to 500-MeV protons in six energy intervals and protons above 600 MeV, (2) a single scintillator that measured 1.4- to 22-MeV protons at five energy thresholds and electrons above 150 keV, and (3) a GM counter telescope that measured proton fluxes above 30 MeV. A complete set of measurements was made every 6.8 min. The experiment operated throughout the active lifetime of the spacecraft. For further details, see Bryant, D. A., et al., Ap. J., v. 141, p. 478, 1965.
