| Abstract | SWICS is designed to determine uniquely the elemental and ionic-charge composition, and the temperatures and mean speeds of all major solar-wind ions, from protons through Fe, at solar wind speeds ranging from 175 km/s (protons) to 1280 km/s (Fe+8). The instrument energy per charge range from 0.16 to 60 keV/e in ~13 min, it combines an electrostatic analyzer with post-acceleration, followed by a time-of-flight and energy measurement. |

| Mission Description | The joint ESA-NASA Ulysses deep-space mission conducted the first-ever out-of-ecliptic study of the
heliosphere - the region of space influenced by the Sun and its magnetic field. The European-built Ulysses
spacecraft was launched by the space shuttle Discovery on the 6th of October 1990, and remained operative
until the 30th of June 2009, covering almost a full 22-year solar magnetic cycle. Wenzel, K.P., Marsden, R.G., Page, D.E., Smith, E.J., The ULYSSES Mission, Astron. Astrophys. Suppl., 92, 2, 207-219, 1992; link to publication |
