The primary Goal of the Solar Wind Ion Analyzer, SWIA, is to measure the Solar Wind Ion Input to the Martian Atmosphere. The secondary Goal is to characterize basic Space Plasma Processes around Mars. SWIA is an Electrostatic Analyzer which makes In-situ Measurements of Ion Energy Flux and Flow Velocities. It can measure Energies from 5 eV to 25 keV, Flow Velocities from 30 km/s to 2000 km/s, and Densities from 0.1 cm^-3 to greater than 100 cm^-3. The Instrument Field of View is 360° × 90° with an Angular Resolution of 22.5°. The basic Measurement Rate is once every 4 s, with continuous Operation except during deep Dips. SWIA is mounted on the MAVEN sun-facing Deck.
