Internal Charging and Secondary Effects
Abstract
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.
These particles have of course very different ranges within materials and many electrostatic situations can be produced according to the particles and materials.
- 1)
What are the properties of materials and configurations that are meaningful in order to observe high internal fields in the system? For example, what are the various forms of conductivity (bulk, surface, radioactivated...) and how can they be measured in the laboratory.
- 2)
What happens to the charge when the voltage builds up (where are they. . .) and when the discharge occurs (single and double layers, where do the charges come from during discharges...)?
