Description

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.
