2.2.6 spase://CDPP/Instrument/AMDA/THEMIS/E/ESA ESA THEMIS-E ESA 2009-05-20T21:10:04Z The THEMIS Electrostatic Analyzers (ESAs) measure 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/Vassilis.Angelopoulos PrincipalInvestigator spase://SMWG/Person/Charles.W.Carlson CoInvestigator spase://SMWG/Person/James.P.McFadden CoInvestigator THEMIS-A Electrostatic Analyzers http://nssdc.gsfc.nasa.gov/nmc/experimentDisplay.do?id=2007-004A-02 Instrument description from NSSDC database spase://SMWG/Instrument/THEMIS-E/ESA ElectrostaticAnalyser Dual Full Distribution Electrostatic Analyzers spase://CDPP/Observatory/AMDA/THEMIS/E
