A number of tests have been performed on two coatings having relatively low αs/ε ratios in order to qualify them for use on the Coronal Diagnostic Spectrometer (CDS). The coatings tested were (i) a 4 μm layer of SiOx on a hand polished aluminium alloy substrate, and (ii) a white Plasmocer [1] coating on an aluminium alloy substrate. The tests performed included the measurement of thermo-optical properties, an evaluation of minimum adhesive strength, the effects of thermal cycling in vacuum and proton bombardment, and resistance to cleaning processes.
