Medium-Energy Neutral-Atom Imager
To detect Energetic Neutral Atoms (ENA) imaging the outflow of medium-energy ions from the polar ionosphere.
Slit-type imager composed of three identical sensors, mounted to a common DPU (Data Processing Unit) assembly, to image the ion populations of the cusp. The instrument determines the time of flight and incidence angle of the incoming ENAs in the energy range 1-30 keV
New development. Working in association with LENA for low-energy and HENA for high-energy
Volumetric exploration of the magnetosphere as the satellite moves along the Highly Eliptical Orbit. Image scanning implemented by combining collimators and satellite spinning
