[7.14] Neutral Gas Distribution in the E-Ring Region of Saturn's Magnetosphere Inferred from Energetic Neutral Atom Imaging

The Ion and Neutral Camera (INCA), as part of Cassini's MIMI investigation, took a unique sequence of Energetic Neutral Atom (ENA) images during Saturn's Orbit Insertion. These ENAs are energetic atoms produced by charge-exchange of energetic magnetospheric ions with magnetospheric neutrals. In our presentation, we will present a first model for the ENA emission from Saturn's E-ring region. Based on direct comparison of model emission with INCA observations, we will provide constraints on the content and distribution of the neutral gas population in this region of Saturn's magnetosphere.
