The effect of 40-keV electron and proton radiation with a flux density of 5 × 10 cm−2 s−1 on the deposition of products of thermostimulated gas release from a polymer composite on a substrate made from protective K-208 glass used for the protection of spacecraft solar panels is experimentally investigated. Analysis of the obtained results shows that, unlike proton radiation, electron radiation results in an increase in the optical density of the glass and stimulates the deposition of gas-release products. It is established that the majority of effects generated as a result of exposure of the substrate to electron radiation are neutralized by protons upon combined irradiation with electrons and protons.
In the paper the problem of space debris. Describes the causes of debris in near-Earth space. Describes the distribution of debris in near-Earth space. Shown that the accumulation of debris consists of two rings. Analyzes the statistics of debris. We analyze the spatial distribution of debris. Conjectured form rings debris in near-Earth space.
Features of formation and migration of radiation-induced defects in carbon nanotubes (CNT) and nanostructured materials are examined. The main methods and software tools used for the simulating nanomaterial structure and space factors are described. The results of mathematical simulation are presented.
