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 Galileo’s 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.
