OGO-E Cosmic Radiation - Nuclear Abundance Experiment

Information on the detailed charge and energy spectra of galactic and solar cosmic rays is required for a better understanding of the production, acceleration and modulation of those cosmic rays. This experiment consists of a set of three detector assemblies to measure the differential energy spectra of protons and heavier nuclei through calcium (Z = 20) in the range of 400 Kev to 1 Bev/nucleon, and an extensive electronics system to implement the logic, perform pulse height analysis, measure particle fluxes, monitor experiment performance and interface with the OGO data system. The detector systems described here are the design of F. B. McDonald, V. K. Balasubrahmanyan, D. E. Hagge, B. Teegarden and G. H. Ludwig of the Goddard Space Flight Center.
