| Zusammenfassung |
| In this study we discuss Neutral Atom emission from Mercury
Magnetosphere. We study those neutrals whose emission is directly
related to the circulation of energetic ion of solar wind origin, via
backscattering process. The environment of Mercury is characterized by
a weak magnetic field; thus, cusp regions are extremely large if
compared to the Earth's ones, and intense solar wind proton fluxes are
expected there. Protons precipitating onto the surface can be
neutralized and backscattered. Such neutrals travel in straight
trajectories and can be detected by remote sensing instrumentation,
thus allowing instantaneous imaging of the proton surface flux. The
feasibility of such a measurement is discussed here: simulated neutral
atom images are investigated in the frame of the Neutral Particle
Analyser - Ion Spectrometer (SERENA NPA-IS) experiment, on board the
ESA mission BepiColombo/MPO. |
