Cosmic Rays

NSSDCA ID: 1962-051A-04

Mission Name: Explorer 14
Principal Investigator:Dr. Frank B. McDonald


The instrumentation for the cosmic-ray experiment consisted of (1) a double scintillation counter telescope 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 6.3 min. The experiment worked throughout the useful life of the spacecraft, October 2, 1962, to August 11, 1963.
