Interplanetary and Solar Electrons 2 keV to > 1 MeV

NSSDC ID: 1978-079A-09
Mission Name: ISEE 3
Principal Investigator: Prof. Kinsey A. Anderson


This experiment was designed to study spectra and anisotropies of interplanetary and solar electrons (2 to 1000 keV) in the transition energy range between solar wind and low-energy cosmic rays. The electrons were measured by a pair of passively cooled, surface-barrier, semiconductor-detector telescopes (approximately 15 keV to approximately 1 MeV) and by a hemispherical plate electrostatic analyzer with channel-multiplier detectors (2-18 keV). Counting rates were sectored into angular sectors about either the magnetic field or the sun direction. The telescope yielded 8 or 16 sectors and the analyzer yielded 16 sectors.
