The Comprehensive Suprathermal and Energetic Particle Analyzer (COSTEP) on the
Solar and Heliospheric Observatory (SOHO) addresses scientific objectives
related to the following phenomena:

Steady state processes in the solar atmosphere
Energy release and particle acceleration in the solar atmosphere
o Long duration events
o Impulsive events
o Non flare-associated particle events
Samples of solar atmospheric material
o Large solar particle events
o Elemental abundance of low-Z-elements
o Isotopic abundances of H and HE
o Small, 3HE-rich flares and impulsive kilovolt electron events
Interplanetary medium
o Travelling shock events
o Corotating interaction regions
o Particle propagation in interplanetary space

The COSTEP sensors Low Energy Ion and Electron Instrument (LION) and Electron
Proton Helium Instrument (EPHIN) allow a systematic investigation of these
questions to be made by measuring energetic particles over a wide range of
energies and for different particle species and combining this information with
simultaneous observations from other experiments in the SOHO payload, on other
satellites and with ground based observations.
