Description
The Solar Wind Ion Composition Spectrometer (SWICS) on Ulysses is designed to
determine uniquely the elemental and ionic-charge composition, and the
temperatures and mean speeds of all major solar-wind ions, from H through Fe,
at solar wind speeds ranging from 175 km/s (protons) to 1280 km/s (Fe8+). The
instrument, which covers an energy per charge range from 0.16 to 59.6 keV/e in
~13 min, combines an electrostatic analyzer with post-acceleration, followed by
a time-of-flight and energy measurement. The measurements made by SWICS will
have an impact on many areas of solar and heliospheric physics, in particular
providing essential and unique information on: (i) conditions and processes in
the region of the corona where the solar wind is accelerated; (ii) the location
of the source regions of the solar wind in the corona; (iii) coronal heating
processes; (iv) the extent and causes of variations in the composition of the
solar atmosphere; (v) plasma processes in the solar wind; (vi) the acceleration
of energetic particles in the solar wind; (vii) the thermalization and
acceleration of interstellar ions in the solar wind, and their composition; and
(viii) the composition, charge states and behavior of the plasma in various
regions of the Jovian magnetosphere.
