Internal Charging and Secondary Effects

  title={Internal Charging and Secondary Effects},
  author={Manola Romero and Leon S. Levy},
The charged particle environment of spacecraft includes as well very low energy plasma (ionospheric cold plasma), storm particles of a few keV and high energy particles trapped in the magnetospheric belts. Initially, only the so called storm particles were held responsible for surface charging and anomalies. Since 20% of the recorded discharges on SCATHA occurred without surface charging, trapped high energy particles are also a matter of concern and interest.
