dc.description.abstract© 2020, Pleiades Publishing, Ltd.Abstract: The processes of erosion and redeposition of plasma-facing materials in fusion devices are some of the most important factors affecting the plasma parameters and the resource of the first wall. The method of analyzing thin layers on a surface using keV-energy proton scattering expands the functionality of determining the rate of erosion and deposition of layers with a large atomic number on a substrate of a light element or, conversely, light layers on a heavy substrate, which is typical of modern fusion installations. The analysis of deposition and/or erosion consists in placing special marker targets with the layers of a material with a low atomic number and/or material with a large atomic number in the places of the installation in which it is proposed to study the rate of erosion and/or deposition, with a subsequent analysis of the energy spectra of hydrogen ions reflected from exposed targets with energies in the kiloelectron-volt range. In this paper, estimates of the applicability of this technique directly in a fusion device with regard to the characteristic parameters of the near-edge plasma are given.
