- 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.
