Extra Slides Summary  Orbit     Europa torus      Location and evolution of energetic particle injections (H+, O+, S+) in 3-300 keV range Acceleration mechanisms determined through spectral evolution of different masses Magnetodisc   Morphology and long-term variations of neutral gas in torus region Simultaneous EUV observations of O, S plasma torus nice complement Short-term variations and distribution of energetic particles (H+, O+, S+) Characterizes Europa’s ion sputtering environment remotely [Leblanc et al., 2005] + remote backscatter Giant accelerator    Equatorial orbits resolve radial and vertical structures well such as thickness and structure of magnetodisc and torus, but very limited azimuthal resolution >20 deg inclination achieves drastically better azimuthal resolution but maintains also vertical resolution and avoid most of the harsh radiation Higher inclination  better for simultaneous radio observations? Thickness, shape and modulations Relation to radio emissions  Correlate global configuration and evolution of magnetodisc and energetic particles, and moons with radio emissions
