Electron and Proton Wide-Angle Spectrometer (EPAS) on the CRRES spacecraft

Abstract

The electron and proton wide-angle spectrometer (EPAS) in the CRRES scientific payload utilizes arrays of solid-state detectors coupled with a magnetic deflection system in order to detect electrons (21-285 keV) and protons (37-3200 keV). The image size of the particles and the angular resolutions are controlled by the width of the entrance hole, the geometry of the pole pieces, and the position of the particles in the image plane. Additional features of the EPAS are described in some detail. Selected in-flight data are shown as an illustration of the instrument performance in the operational orbit.
