To assess the effect of dielectric charging on the performance of operational spacecraft, consideration must be given to extending laboratory simulations and measurements to operational conditions. Some of the key issues that must be addressed are the scaling of discharge characteristics from laboratory simulation exposure fluxes to the expected fluxes in space and the scaling from laboratory-sized objects to satellite-sized objects. This paper presents results of a recent experimental investigation, part of which addresses these issues. Twelve- and 36-inch-diameter 2-mil Kapton samples, a 24-inch-square Kapton thermal blanket, a 36-inch 4-mil fiberglass sample, and a secound-surface mirror array were exposed to 25-keV electrons. Measurements were made of the discharge current and time history, blowoff current and time history, and the surface potential before and after discharge.
