发明名称 METHOD FOR EVALUATING A LOSS OF MASS AND A CONTENT OF VOLATILE CONDENSING SUBSTANCES UNDER THE ACTION OF A VACUUM AND HEAT ON NONMETALLIC MATERIALS IN COMBINATION WITH HIGH-ENERGY RADIATION AND DEVICE FOR IMPLEMENTING SAME
摘要 The invention relates to a method for evaluating a loss of mass and a content of volatile condensing substances formed on heating of nonmetallic materials in a vacuum and under the action of high-energy radiation on the products of gas evolution. The problem addressed by the method consists in evaluating a loss of mass and a content of volatile condensing substances formed when modeling factors of outer space whilst extending the range of factors: high-energy ionizing radiation in the ultraviolet and vacuum ultraviolet regions. The evaluation of the contamination capacity of the products of gas evolution of a material is performed on the basis of parameters of contaminating films (uniformity and thickness) on optical surfaces, the chemical composition and mass of a condensed deposit. Sheets of glass for external lenses and mirrors of optical units in the temperature range of from -30 to +120°? are used as condensing sheets. The vacuum ultraviolet radiation exposure has a wavelength range of from 115 to 320 nm and a spectral power density of from 10-10 to 10-5 W/cm2°nm. The problem addressed by the device consists in ensuring that the gas-evolving material itself and a substitute sample are not subject to the exposure. The apparatus comprises a thermostatic device for the substitute sample and an emitter. The axis of radiation is perpendicular to the axis "material sample - substitute sample of the optical surface" and intersects the section of this axis between the samples in the center.
