ULTRAVIOLET EFFECTS ON SPACE VEHICLE OPERATION IN ULTRAHIGH VACUUM ENVIRONMENT, SEPTEMBER 22, 1960 TO MARCH 21, 1961
Abstract
The effects of solar extreme UV radiation (1100 to 2000 Angstroms) is being studied by 2 methods: (1) an experimental study to find gross effects on polymers, paints, and metallicALLOYS USED IN SPACE VEHICLE OR SPACE SIMULATOR CONSTRUCTION; (2) a theoretical study to find the significance of photoemission and UV-induced outgassing on the performance of the space vehicle and the space simulator. A UV source was developed giving an effective output of 3 x 10 to the 15th power photons/sec in the range from 1100 to 1850 Angstroms with an ultrahigh vacuum system capable of operating in the low 10 to the -9th Torr (mm Hg) range. Irradiation effects including outgassing of plastic samples of Mylar, Teflon, and Plexiglas are given.
