- Abstract
- We studied the kinetics of changes in the diffuse reflectance spectra and the integral absorption coefficient of solar radiation of the original CaSiO powder with micron-sized grains and modified with CeO nanoparticles at their optimal concentration of 3 wt% under electron irradiation (energy Е = 30 keV, fluence Φ = (1 - 7)×10 cm) and the possibility of recording these properties in a vacuum at the irradiation site (in situ). Modification was found to lead to an increase in radiation resistance from 2.39 to 2.89 times depending on the electron fluence. The modification efficiency increases with increasing electron fluence during irradiation. The obtained results can be used to develop new radiation-resistant thermal control coatings of the "optical solar reflectors" class for spacecraft.
