ABSTRACT:
A dielectric film is provided with a metallic back layer for use as the outer layer in a multi layer "thermal blanket" employed as part of the temperature control system for a spacecraft. The dielectric film is repeatedly punctured from the metallized side in order to produce a plurality of small holes, which collect a disproportionately large current from the plasma and adjacent charged surface. The rough edges of these holes also act to initiate frequent, small, field emissions, thereby preventing large surface potentials from building up in the presence of a "hot" space plasma or electron beam environment.
