Results from a comprehensive and systematic study of the energetic electron
population obtained by Cluster observations in the near-Earth magnetotail
plasma sheet will be presented. Data from the Cluster CIS and
FGM instruments are used to determine plasma sheet intervals and the electrons are measured with the RAPID instrument. The
energetic electron spatial distribution and dependence on magnetospheric activity and external drivers, their occurrence
rates and their spectral and pitch angle properties will be investigated. Based on these results one can investigate details
of the source
and transport mechanisms for the energetic electrons. Is there a systematic
cross tail spectral dependency indicating acceleration in a cross tail
potential? Is the statistical phase space density distribution consistent with
radial adiabatic transport? Knowing the answers to these questions may help us understand to what degree or if at all the
magnetotail electrons can act as a
source for the inner radiation belt.
