Abstract:

A charged particle scintillation spectrometer with a geometric factor of 350 sq cm-sr has been built and flown in polar orbit aboard the Air Force Space Test Program Flight 72-1 Satellite. The primary purpose of the sensor is to measure low-intensity solar proton fluxes over the polar caps, in the energy range of 1-15 MeV. Incorporated in the circuitry is a pulse-shape discrimination scheme enabling the instrument to differentiate between protons and electrons. A second pulse-shape discriminator prevents analysis of signals produced by particles which penetrate the primary CsIT1 Scintillator and produce light in a backing layer of fast scintillating plastic.
