Associated Platforms ACE Related Data Sets View all records related to this instrument Description 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.
