INITIAL RESULTS FROM A COMBINED SPACE ENVIRONMENT EFFECTS CHAMBER

Abstract

A combined environment research chamber has been designed and built to provide the capability of irradiating test samples with protons, electrons, and electromagnetic radiation, individually, sequentially, or simultaneously, in a clean high vacuum utilizing a multisample holder and an in situ spectral reflectance measurement technique. The chamber performance was evaluated on the basis of a combined environment test conducted on a titanium dioxide-methyl silicone thermal control coating and was found to be completely satisfactory. In the combined environment experiment, samples of the thermal control coating were exposed individually to vacuum, protons, electrons, electromagnetic radiation, and to all of these constituents simultaneously. No synergistic effects were noted. However, a combined environment interaction was noted wherein the sum of the individual effects was greater than that obtained in the simultaneous exposure.
