A Solid State Detector Experiment for Electron Measurements on OGO-F

A solid state detector system is described which has been developed for flight on an Orbiting Geophysical Observatory in polar orbit. Measurements will be made of the electron flux and spectra above 35 KeV, both for precipitating and locally mirroring electrons, as well as atmospheric backscatter. This paper reviews the physical need and the design requirements of such an experiment; and describes the detector and electronic implementation of the experiment including the methods of monitoring detector and electronic performance in flight.
