AbstractThe observing method that uses ENA (Energetic Neutral Atoms), produced by ion beam injected from an ion thruster, is studied and researched in order to estimate the density of neutral particles in the upper atmosphere. The ion beam experiences charge exchange collision (CEX) with neighboring neutral particles to transform into ENAs. The ENA preserves the information about the particles concerned with those collisions. A new method of estimating the density and the composition of the neutral particles from measuring the ENAs are proposed and the usability by simple calculation and experiment are examined.
