内容記述 | Aluminum/aluminum alloy is a promising material for vacuum components in D-T burning experimental devices owing to its low activation toward 14 MeV neutrons, low outgassing and other features. Prior to its application, however, fundamental interactions between aluminum and fuel (deuterium and tritium) must be understood in regard to tritium inventory, fuel recycling, and environmental safety. For this purpose, a study was made of trapped states and diffusion of deuterium implanted into aluminum using computer-aided x-ray photoelectron spectroscopy (XPS) and secondary ion mass spectroscopy (SIMS). Following deuterium ion implantation (5 keV), a new secondary ion peak, AID+, was detected in the SIMS spectra, indicating deuterium atoms to be directly trapped on aluminum atoms. Changes in the profiles of implanted D atoms in sample at a given temperature were examined by shape analysis using diffusion control model. The diffraction coefficients of deuterium were determined from changes in depth profiles as about 10-16 (at R.T.) and 10-14[cm2/sec](at 70℃). These value are 4 to 8 orders of magnitude lower than those for Fe or Ni; thus aluminum alloys should be superior to tritium in thermonuclear devices than Fe-based materials such as stainless steel. | |||||
