Abstract

As part of a program to develop highly reflective mirrors for applications with space-borne HF lasers, six candidate multilayer coating designs were subjected to a simulated space environment consisting of the combined effects of electron, proton, and solar UV radiation. Particle and UV rates were chosen to be only slightly accelerated over actual space conditions, and the particle energies were chosen to have appropriate penetration depths in the multilayer designs. The sample temperature was controlled and the radiations conducted in an oil-free, vacuum environment in order to minimize thermal and contamination effects. The results for two designs found to be stable - (Si,A1203)2Ag and (Si,Si0x)nAg - and a third relatively unstable design - (ZnS,A1203)4 - are discussed in this paper.
