Dielectric Charging in Space: Ground Test Data and Model Verification

Abstract
A computational model of the charging of dielectrics by electron irradiation has been verified by comparison with ground-based test data. Recent improvements to the model are described briefly. Model calculations are compared with a variety of ground-based test data. The test data span a range of electron energies, from a few keV to beyond 1 MeV. Several experimental configurations are examined. Agreement between computational and experimental results is good.
