- The High-Energy Neutral Atom (HENA) imager on the IMAGE spacecraft detects
energetic neutral atoms (ENAs) in the 10-500 keV energy range. HENA imaging
focuses principally on the ring current, inner plasma sheet, and substorm
injection boundary. HENA is a modified version of the Cassini INCA instrument,
which will provide global images of ENA emissions from Saturn's magnetospheric
ion populations. The HENA lead investigator is Donald G. Mitchell, of the
Applied Physics Laboratory.
