AMPTE/UKS 3-D Plasma Analyzer

The objective of the 3-D Plasma Analyzer instrument was to study the three-dimensional ion distributions in the plasma clouds, the solar wind, the magnetosphere, and the boundaries between them and to measure these distributions with high time and angular resolutions. The instrument consisted of a pair of 270° spherical electrostatic energy analyzers with micro-channel plate detectors that measured the three-dimensional energy/charge distribution of positive ions from 10 eV/q to 20 keV/q over the polar angle range 0° to 180° with respect to the spin axis of the spacecraft. A complete set of measurements was obtained every 5 s spin period.
