Carbon and Tungsten Effect on Characteristics of Sputtered and Re-deposited Beryllium Target Layers under Deuteron Bombardment

摘要

The behavior of the plasma facing Be-elements in the International thermonuclear experimental reactor ITER will be affected by the re-deposition of other eroded plasma facing materials. The effect of carbon- and tungsten-additions on the microstructure, chemical composition and hydrogen isotope accumulation in the sputtered and re-deposited layers of beryllium TGP-56 at its interaction with 200-300-eV hydrogen isotope ions was studied in the MAGRAS facility.
