INVESTIGATION OF THE CONTAMINATION OF REFLECTOR SURFACES OF INFRARED RADIATORS TO BE USED IN SPACE SIMULATORS
Abstract
An investigation was made of a reflector of a bare-tungsten-sourced infrared radiator in high vacuum. The reflector became overcoated with a multicolored film which seriously deteriorated the efficiency of the radiator. A series of experiments of a qualitative nature was performed to determine which gases commonly found in oildiffusion-pumped high vacuum systems were involved in the production of the contaminating film. Evidence concerning the chemical nature of the film was obtained by having a sample analyzed by electron diffraction techniques, and certain recommendations are made to help ensure the successful operation of bare-tungsten-sourced infrared radiators in high altitude test chambers.
