RBSPICE Instrument
Each RBSPICE instrument (one on each of two satellites) is a time-of-flight versus energy spectrometer. The spectrometer measures medium energy protons, electrons, and ions (H+, He+, and O+) as functions of energy and angle, as well as measurements of electrons, to be used for diagnostic purposes. Spacecraft rotation permits sampling over the full 160o range of look directions in three dimensions.
This data helps determine how space weather creates the storm-time ring current around Earth, how that ring current supplies and supports the creation of the radiation belt populations, and how it can also quickly reduce radiation belt particle intensities.
