Mission Name: IMP-GThis experiment was designed to observe positive ion intensities in the solar wind, within the magnetosheath, and in the geomagnetic tail using a modified low-energy proton and electron differential energy analyzer (LEPEDEA detector). The detector, which was composed of curved plate electrostatic analyzers and continuous channel multipliers ("channeltrons"), was designed to measure differential energy spectra and angular distributions of low-energy positive ions over the energy range 90 eV to 12 keV. The detector was an analog device and, therefore, was read continuously during the flight. Energy measurements were obtained within 32 individual energy intervals over the proposed range and at 16 sun-referenced azimuthal directions perpendicular to the spacecraft spin axis for each energy interval. The experiment performed normally for about two and one half months from launch when the experiment power supply failed.
