Abstract
This article assesses the trapping and concentration of helium and hydrogen ions in a titanium base-aluminium-vanadium alloy under conditions encountered in a thermonuclear reactor. Prior annealing and bombardment with argon ions were both found to decrease helium and hydrogen capture in the vacancies of the alloy. Concentration profiles occurring at different implantation temperatures are graphed. The study was carried out with the nuclear recoil method using nitrogen ions accelerated in a U-120 cyclotron.
