Medium Energy Cosmic Rays, 1-500 MeV/n, Z = 1-28; Electrons: 2-10 MeV

NSSDCA ID: 1978-079A-04

Mission Name: ISEE 3
Principal Investigator:Dr. Tycho T. Von Rosenvinge

Description

This experiment was designed to study the composition of solar cosmic rays from hydrogen through iron and the elemental abundance of galactic cosmic rays. Three cosmic-ray telescopes, plus a proportional counter for measurement of electrons and X rays, comprised the instrumentation. Nuclei with Z between 1 and 30 were measured in various energy windows in the range 1 to 500 MeV/nucleon. Unit mass resolution was obtained for isotopes with Z equal to 1, 2, and 3 to 7 in the energy ranges 4 to 70, 1 to 70, and 30 to 140 MeV/nucleon, respectively. Electrons were measured in the energy range approximately 2 to 10 MeV. Anisotropy information was obtained for the electrons and nuclei with Z equal to 1 to 26.
