2.2.6 spase://CDPP/Instrument/AMDA/Cassini/CAPS CAPS Cassini Plasma Spectrometer 2009-05-20T21:10:13Z CAPS consists of three sensors, all mounted on a common scanning platform: the Electron Spectrometer (ELS), which measures the flux of electrons as a function of energy/charge and aperture entry direction. Its energy range is 0.7 eV to 30 keV. the Ion Beam Spectrometer (IBS), which measures the flux of positively charged ions of all species as a function of energy/charge and aperture entry direction. Its energy range is 1 eV to 50 keV. the Ion Mass Spectrometer (IMS), which provides species-resolved measurements of the flux of positively charged atomic and molecular ions as a function of energy/charge vs. aperture entry direction. Its energy range is 1 eV to 50 keV. PrincipalInvestigator ElectrostaticAnalyser spase://CDPP/Observatory/AMDA/Cassini
