The Solar Wind Ion Composition Spectrometer (SWICS) and the Solar Wind Ions
Mass Spectrometer (SWIMS) instruments on the Advanced Composition Explorer
(ACE) are optimized for measurements of the chemical and isotopic composition
of solar and interstellar matter. Both instruments are time-of-flight mass
spectrometers with electrostatic analyzers, though each is optimized for
different measurements. SWICS determines the chemical and ionic charge state
composition of the solar wind and resolves H and He isotopes of both solar and
interstellar sources. SWICS also measures the distribution functions of both
the interstellar cloud and dust cloud pickup ions up to energies of 100 keV/e.
SWIMS measures the chemical and isotopic composition of the solar wind for
every element between He and Ni, up to 10 keV/e.
SWIMS and SWICS was designed and developed by the University of Michigan, Ann
Arbor, Solar and Heliospheric Research Group.
