PDS: The Planetary Atmospheres Node
- Determine electron impact ionization rates
- Measure magnetic topology via loss cone measurements
- Measure primary ionospheric photoelectron spectrum
- Measure auroral electron populations
- Evaluate plasma environment
The Solar Wind Ion Analyzer (SWEA) is placed at the end of a 1.3-m boom, which allows a large, clear field of view and minimizes the spacecraft influence on the electrons arriving at the detectors. SWEA utilizes the classic Berkeley top hat hemispherical ESA design with a FOV 360° X 130° field of view.
Measurement Objectives
SWEA measures the energy and angular distributions of 2 eV to 6 keV solar wind and magnetosheath ions and ionospheric photoelectrons to:
