- The Solar Wind Experiment (SWE) on WIND will measure ions and electrons in the
solar wind and the foreshock regions (particles whose energies are in the
kiloelectronvolt range). From these measurements, the solar wind velocity,
density, temperature and heat flux can be deduced. Electron and ion velocity
distributions should reveal properties of the following plasmas and their
pivotal role in the transfer of mass, momentum, and energy from the Sun to the
Earth. Measurements made in the foreshock region will contribute to
understanding the structure of the bow shock.
The SWE instrument consists of five integrated sensor/electronics boxes and a
data processing unit (DPU). The sensor units are mounted on the top and bottom
shelves of the spacecraft, extending through the top and bottom surfaces.
3D velocity distribution measurements of the ion component in the solar wind
are made by a pair of Faraday Cup analyzers, which provide a wide field-of-view
and the capability for flow characterization within one spin revolution (3
seconds). 3D velocity distribution measurements of ions and electrons in
plasmas having Mach numbers.
