2.3.1 spase://CNES/Instrument/CDPP-AMDA/Rosetta/ICA ICA Ion Composition Analyser 2009-05-20T21:10:13Z The Ion Composition Analyzer (ICA) flown on Rosetta provides ion measurements in the energy range 0.01 - 36 keV/q for the main ion components H+, H2+, He+, O+, and for the group of molecular ions with M/q ration between 20 and 80 amu/e. ICA has a 90 deg x 360 deg field of view. Electrostatic sweeping performs elevation (+/- 45 deg) coverage. The IMA sensor is a spherical electrostatic analyzer followed by a circular magnetic separating section. A large diameter MCP with a discrete anode images the matrix azimuth x mass. spase://SMWG/Person/Stas.Barabash PrincipalInvestigator MassSpectrometer spase://CNES/Observatory/CDPP-AMDA/Rosetta
