Non-arcing dielectric modular array

摘要

A non-arcing modular dielectric array having an electrically conductive substrate mounting a multiplicity of spaced dielectric elements, such as second surface mirrors or solar cells, with outer dielctric surfaces spaced and electrically isolated from the substrate which tend to accumulate electrical charges in a plasma environment creating between the substrate and element surfaces large potential differences which induce arc discharges between the surfaces and substrate. The gaps between adjacent dielectric elements are filled with a resilient filler which provides about the individual elements conductive frames grounded to the substrate for bleeding charges from the element surfaces to the substrate to suppress arc discharges therebetween.
