Simulation of Interaction between Hydrogen Isotope Ions and Beryllium Elements of Constructions

Tests, involving bombardment of beryllium targets with hydrogen and deuterium ions, were conducted to analyze the efficiency of construction elements facing plasma conditions. Various experimental conditions were realized including the intense redeposit of erosion products. The following has been studied: component and phase composition and microstructure of pollinated and sprayed beryllium layers, accumulation of hydrogen isotope atoms in them, and also processes of repeated sputtering onto the beryllium and tungsten targets and effect of these processes on the deuterium accumulation in sprayed and redeposited layers.
