Dependence of Electron Flux on Electron Temperature in Spacecraft Charging

Abstract

Two important observations when the onset of spacecraft surface charging occurs are (1) the electron flux measured in the high-energy (above several keV) channels onboard rises and (2) the ambient electron temperature rises above a critical value. We show by means of an analytical model that the two behaviors are consistent with each other.
