Prediction of Materials Charging in Magnetospheric Plasmas

Basic materials charging in magnetospheric plasmas may be predicted based on material properties that define capacitance, conduction, and emission for the surface, and on plasma species, temperatures and densities. This report summarizes results obtained using MATCHG, a program that embodies the bas...

Description
Summary:Basic materials charging in magnetospheric plasmas may be predicted based on material properties that define capacitance, conduction, and emission for the surface, and on plasma species, temperatures and densities. This report summarizes results obtained using MATCHG, a program that embodies the basic formulations of the NASCAP program without the 3-dimensional (3-D) complexities. Plasma temperature and material property variation effects on surface potentials are considered. A graphical procedure for predicting voltage response from the general no bulk conductivity characteristics is presented. (Author)
