Scattering characteristics and imaging of energetic neutral atoms from the Moon in the terrestrial magnetosheath

Barabash, Stas; Futaana, Yoshifumi; Wieser, Martin +6 more

We study hydrogen energetic neutral atom (ENA) emissions from the lunar surface, when the Moon is inside the terrestrial magnetosheath. The ENAs are generated by neutralization and backscattering of incident protons of solar wind origin. First, we model the effect of the increased ion temperature in the magnetosheath (>10 times larger than that…

A family for miniature, easily reconfigurable particle sensors for space plasma measurements

Barabash, S.; Wieser, M.

Over the last 15 years the Swedish Institute of Space Physics developed a line of miniaturized ion mass analyzers for space plasma studies with masses of 400-600 g and highly compact and dense design to minimize the volume. The sensors cover an energy range from few eV up to 15 keV and reach an angular coverage up to hemispherical and mass resolut…
