BackForwardInstrument:  LIA 

Instrument details
Acronym LIA
Full name Light Ion Analyser
Purpose LIA will help investigate the properties and behaviour of the solar wind, as well as the behaviour of Earth's magnetosphere where it meets the solar wind
Short description
  • LIA is designed to measure the ion velocity distribution function within an energy range of 5 eV up to 25 keV.
  • LIA is 2 identical 2 sr fov instruments mounted on opposite sides of the spacecraft platform, providing a combined 4 sr instantaneous field-of-view.
  • Each LIA consists of a top-hat electrostatic analyzer, electrostatic aperture deflectors, and a microchannel plate detector for analyzing the energy, direction, and flux of ions.
