The Optical Degradation Characteristics of the Nanoparticles-Modified BaSO4 Powder under Irradiation with Electrons and Protons
Статья в журнале
The work presents the study of synergistic effects in changing of 1) the diffuse reflectance spectra within 0.2-2.2 µm and 2) the solar absorptance of barium sulfate (nBaSO4) modified by silicon dioxide nanoparticles under separate and simultaneous irradiation with 30 keV electrons and 5 keV protons. The spectra were recorded before and after each irradiation period in vacuum at the site of irradiation (in situ). It was found that the change in optical properties of the powder under simultanous irradiation is larger in comparison with the total change under separate irradiation, with the values of electron fluence varying up to Fе=9•1016 cm-2 and the values of proton fluence varying up to Fр=6•1016 cm-2. The difference reaches 1.24 times. The work provides the description of formation and accumulation of absorption centers under separate and sumultaneous irradiation of nBaSO4.
