High-Energy Neutral-Atom Imager
To detect Energetic Neutral Atoms (ENA) imaging the ring current, inner plasma sheet, and substorm injection boundary
Slit-type imager measuring the velocity of the ENAs that it detects by measuring their time of flight (TOF) and trajectory through the sensor. Energy range 10-500 keV
New development. Working in association with LENA for low-energy and MENA for medium-energy
Volumetric exploration of the magnetosphere as the satellite moves along a polar Highly Eliptical Orbit.
