Abstract: The samples of tungsten with a purity of 99.5 and 99.7% were irradiated with helium ion beams (EHe+ = 0.12 MeV). The total sputtering coefficients for the sample depth up to 60 Å from the surface of sample were obtained. It was found that on the surface of tungsten, the number of pits (the flecking effect) significantly exceeds the number of bubbles (the blistering effect). The damage profiles of the surface of tungsten as a result of irradiation with helium ions are calculated. The areas of maximal display of… Show more

Helium ion beams with energies EHe+ = 0.12 and 4 МeV were used to irradiate samples of tungsten with a purity of 99.7%. Graphs of coefficient of the ionization, coefficient of production of phonon and vacancies are obtained. These processes occurred as a result of irradiation. The differential and integral curves of the sputtering coefficient from the surface of samples of tungsten were constructed, that allowed to determine the number of recoil atoms that reached the surface. The total coefficients of displacements on the surface of the samples were calculated. These characteristics are compared with similar characteristics obtained by irradiating of samples of tungsten (tungsten samples) with a purity of 99.5% with helium ions (0.12, 4 MeV). Areas in which the characteristics are similar and areas where these characteristics differ are marked.
