Abstract:
Application of ion beam analysis techniques in the studies of material transport and fuel inventory in the controlled fusion devices is exemplified. Enhanced proton scattering on the carbon isotopes ¹²C(p,p)¹²C, ¹³C(p,p)¹³C and secondary ion mass spectrometry allowed for determination of carbon erosion and re-deposition on the wall components following the experiments with a tracer (¹³CH4) injection into the plasma edge at the TEXTOR tokamak. For the assessment of the deuterium fuel accumulation in the plasma facing components depth profiling by means of nuclear reaction analysis, ³He(d,p)4He, was performed. Advantages and limitations of those nuclear methods in solving experimental problems are addressed.
