1 November 1993 Contamination effects on EUV optics in the space environment

The Coronal Diagnostic Spectrometer (CDS) to be carried on the joint ESA/NASA solar observatory satellite, SOHO, in late 1995 operates in the extreme ultra-violet (15 - 80 nm) and is thus particularly vulnerable to molecular contamination of the optical surfaces. Such contamination arises from materials present in the assembly and test environment and also from outgasses products from the various elastomers and other non-metals used for instrument construction. The need for secure surfaces free from contamination and the requirement for very low optical scatter drives the need for a comprehensive system of contamination control. We present our current work from a study in which we are attempting to identify typical contaminants found in space instrumentation, to understand and characterize their properties and to measure effects on the performance of an EUV optical system.
