N2 - The retention of helium and deuterium in tungsten irradiated with a high-intensity plasma flux (~1024 m−2 s−1) using either helium or deuterium ions is studied. Irradiation is carried out at a temperature of 480 K. Recrystallized and plastically deformed samples are used to detect the effect of the initial microstructure on plasma confinement and release. Thermal-desorption spectroscopy is performed to reveal the stages of release and for quantitative determination of the retention integral for both types of samples. A comparison of the recrystallized and plastically deformed samples is performed to determine the effect of plastic deformation (expressed in a high dislocation density and dislocation networks) on the confinement and release of plasma components. It is demonstrated that plastic deformation causes a significant decrease in helium retention, and, conversely, an increase in the capture of deuterium.
