Ion and Neutral Camera
The Ion and Neutral Camera (INCA), provided by the Johns Hopkins University
Applied Physics Laboratory with help from other Co-Investigator institutions,
obtains remote, images of the global distribution of energetic ions for
energies from 7 keV/nucleon to 8 MeV/nucleon, discriminated according to
energy and mass species (Oxygen and Hydrogen). To obtain these images INCA
measures the arrival directions, energy, and mass species of Energetic
Neutral Atoms (ENA's) using the new technique of ENA imaging
(see Energetic Neutral Atom Imaging). INCA also can be commanded
to obtain very high sensitivity ion measurments, providing the angular, energy, and
species (O and H) distributions of in-situ ions. The measurement technique is
described more fully in the first figure caption below. INCA is mounted on
the body of the spacecraft (see Spacecraft Diagram and Spacecraft Photo), and its 120 deg. by 90 deg. field of view is centered on the spacecraft -Y axis. INCA has a mass
of 6.92 kg and consumes about 3.0 W of nominal power. Its volume envelope is about
XXX by YYY by ZZZ cm.
