Description
In experiments with magnetically confined hydrogen plasmas (including its isotopes; deuterium and tritium), as investigated in controlled thermonuclear fusion research, hydrogen isotopes, ions and energetic neutral atoms, at energies ranging from a few eV to keV are continually bombarding the first wall materials of the vacuum vessel. The assessment of the extend of the ion implantation into the first wall materials, as well as the erosion and re-deposition of the sputtered wall material including the evaluation of its hydrogen content is of paramount importance. In this regard, a brief summary and the basic principles of the main surface analysis techniques used under Fusion Technology will be presented, as well as some non-destructive nuclear reaction methods.
