Аннотация:Simulation tests of radiation stability of various thermal control coatings under proton irradiation with particle energies 100-500 keV and particle fluences 10 14-2 × 10 16 cm -2 were done in the Skobeltsyn Institute of Nuclear Physics of Moscow State University on a proton accelerator. Experimental data on change of As of paint coatings and mirror coatings as a function of proton fluence and energy are presented. Prediction of As changes of the coatings under the impact of proton radiation with distributed energy spectrum in space flight based on ground test results with monoenergetic proton beams is discussed. Estimates of coating degradation in geosynchronous orbit are made in terms of the mathematical model of degradation
