Instrument details
Acronym ENAI
Full name The Energetic Neutral Atom Imager
Purpose ENAI is used for imaging observations of neutral atoms (H, O) with energies ranging from 10 to 500 keV in the source region of magnetic storms, achieving high temporal, spatial, and energy resolutions.
Short description
