2.2.6 spase://CDPP/Instrument/AMDA/THEMIS/C/ESA ESA 2017-03-20T21:10:04Z The THEMIS Electrostatic Analyzers (ESAs) measures the flux of thermal particles in a 360° field of view over the energy range from ~3 eV to 30 keV. There are two ESAs on each THEMIS spacecraft, one measures ions, the other electrons. The ESA measures the full 3-D distributions, as well as the density, velocity, and temperature of the ambient electrons and ions. NASA contract NAS5-02099 and V. Angelopoulos for use of data from the THEMIS Mission. Specifically: C. W. Carlson and J. P. McFadden for use of ESA data. spase://SMWG/Person/Charles.W.Carlson CoInvestigator spase://SMWG/Person/James.P.McFadden CoInvestigator NSSDC description http://nssdc.gsfc.nasa.gov/nmc/experimentDisplay.do?id=2007-004A-02 Instrument description from NSSDC database UCLA description http://themis.igpp.ucla.edu/instrument_esa.shtml Instrument description from UCLA spase://SMWG/Instrument/THEMIS-C/ESA ElectrostaticAnalyser spase://CDPP/Observatory/AMDA/THEMIS/ThemisC
