Charging Control Satellite Materials. Part 1
Abstract
Thin film coatings of indium oxide (IO) and indium tin oxide (ITO) on thin sheets of FEP Teflon and Kapton are evaluated as thin conductive transparent coatings. Deposition parameters necessary to optimize the coating surface resistance, solar absorptivity and stability are discussed in detail. Materials are coated over 30 cm square areas by reactive magnetron sputtering to achieve reproducible uniform coatings. Uniformity, deposition rate, coating thickness, oxygen partial pressure, insitu RF and DC biasing, and chamber conditioning are examined in detail. The charge control properties of the IO and ITO coated polymers are evaluated and demonstrated in a facility which provide a multiple energy electron radiation environment with energies up to 30 KeV at current densities in excess of 2nA/sq cm.
