“…In the course of bombarding the tungsten coatings with D + or He + ions, there arise radiation defects of various types in them: defects in the material crystal lattice and impurities in the form of implanted ion beam particles. In order to determine the origin of the generated radiation defects, we, as was done earlier in works [27,28,33,38,39], analyzed the capture, migration, and release of implanted deuterium and helium particles from the specimens into vacuum with the help of thermal desorption spectra. In particular, this method was used, when determining the activation energy of the thermal desorption in the main peaks of particle release spectra.…”

The capture, retention, and thermal desorption of deuterium and helium ions with medium energies implanted into tungsten-coated multilayer functional structures and the formation of corresponding radiation-induced damages in the crystal lattice of the tungsten coatings of those structures have been studied making use of the thermal desorption spectroscopy and electron microscopy methods. The behavior of deuterium and helium in the examined materials and its dependence on the post-implantation heating temperature, the dose of irradiation with D+ and He+ ions, and the irradiation condition – separate (making use of ions of only one kind) or sequential (making use of ions of both kinds) – are analyzed. A classification of radiation-induced defects and mechanisms of their annealing are proposed.

The analysis of main published results of studies of retention and migration of ion-implanted hydrogen isotopes and helium in tungsten and tantalum coatings, formation of radiation damages of the crystal lattice and their interaction with implanted gases, as well as the influence of helium and deuterium on various properties and surface morphology of coatings was carried out. The irradiation of samples was performed by beams of accelerated ions of hydrogen isotopes or He+, and in a plasma containing these ions, at various fluences and energies of incident ions, and at various temperatures of targets during implantation. Special attention was paid to the research results obtained at simultaneous irradiation of W both in bulk and in thin-film form. The used methods were electron microscopy, reemission mass spectrometry, thermal desorption spectrometry, X-ray photoelectron spectroscopy, X-ray diffraction, nuclear reaction analysis and Rutherford ion scattering.
