Abstract
The Galileo mission was the first to orbit Jupiter and lasted from 1995
to 2003. Its data set is unique even compared to contemporary data from
the Juno mission since Galileo had an equatorial orbit, as it is
necessary to sample equatorially mirroring particles. Galileo also had
several close moon flybys. It carried instrumentation designed to
provide measurements of MeV electrons. Different to for example optical
instruments that can also respond to such particles, an instrument
designed to measure radiation is much more straightforward to calibrate.
Here we describe Galileos EPD suite (Energetic Particle Detector) and
its measurements. EPD measures energetic charged particles roughly in
the energy range of tens of keV to tens of MeV while distinguishing
particle species. This document fills in gaps in the EPD documentation
and summarizes already published information. We describe the content of
the newly delivered PDS data and how the data has been processed. At the
end we also show sample data, explain typical features and possible
pitfalls.
