Advanced Composition Explorer
Encyclopedia : A : AD : ADV : Advanced Composition Explorer
Advanced Composition Explorer (ACE) is an Explorer satellite mission to study matter in situ, comprising energetic particles from the solar wind, the interplanetary medium, and other sources. It was launched August 25 1997 and is currently operating at the L1 Lagrange point.
Instrumentation
Cosmic Ray Isotope Spectrometer (CRIS): CRIS determines the isotope composition of galactic cosmic rays. It designed to be sensitive enough to detect isotopes up to the range of zinc (Z-30).
ACE Real Time Solar Wind (RTSW):
Solar Wind Ion Mass Spectrometer (SWIMS) and Solar Wind Ion Composition Spectrometer (SWICS): These two instruments are time-of-flight mass spectrometers, each tuned for a different set of measurements. They analyze the chemical and isotopic composition of solar wind and interstellar matter.
Ultra-Low Energy Isotope Spectrometer (ULEIS): ULEIS measures ion flux and is sensitive to a range from helium through nickel to determine the makeup of solar energetic paritcles and the mechanism by which the particles become charged by the sun.
Solar Energetic Particle Ionic Charge Analyzer (SEPICA):
Solar Isotope Spectrometer (SIS):
Solar Wind Electron, Proton and Alpha Monitor (SWEPAM):
Electron, Proton, and Alpha-particle Monitor (EPAM):
Magnetometer (MAG):
