| 内容記述 | Determination of the nature and degree of contamination of mirrors in a vacuum environment in the presence of UV irradiation by outgases from some materials that are candidates for use inside spacecraft and simulated spacecraft environments. A vacuum apparatus was developed for testing contamination of mirrors. Offgases from heated test materials are deposited on a refrigerated mirror, half of which is UV irradiated. Reflectance is measured between 1100 and 25,000 A. Thermofit RNF-100, insulated wire TRT-24-19-V-93, and Eccofoam FS and FPH gave heavier deposits on the nonirradiated mirror. Moxness MS60 SO8, Scotch Tape Y-9050, RTV-577, RTV-41, Stycast 1090, and Epon 934 and 828 gave heavier deposits on the irradiated mirror. Raychem wire 44/0411, polyimide tape X1156, Insulgrease G-640, High Vacuum Silicone Grease, and RTV-602 gave only slight deposits on the irradiated and nonirradiated areas of the mirror. |
