“…NRA complements results of the gas balance assessment in fusion devices [50,79,106,107] and thermal desorption spectroscopy (TDS) data [108] to obtain an overview of the global fuel retention. Determination of the fuel content in PFMC is crucial to obtain reference targets in the development of in-situ techniques: laser-induced desorption (LIDS), breakdown (LIBS) or ablation (LIAS) spectroscopy techniques [109][110][111][112][113][114].…”

A brief overview of ion beam analysis methods and procedures in studies of materials exposed to fusion plasmas in controlled fusion devices with magnetic confinement is presented. The role of accelerator techniques in the examination and testing of materials for fusion applications is emphasised. Quantitative results are based on robust nuclear data sets, i.e. stopping powers and reaction cross-sections. Therefore, the work has three major strands: (i) assessment of fuel inventory and modification of wall materials by erosion and deposition processes; (ii) equipment development to perform cutting-edge research; (iii) determination of nuclear data for selected ion-target combinations. Advantages and limitations of methods are addressed. A note is also given on research facilities with capabilities of handling radioactive and beryllium-contaminated materials.

“…NRA was used to determine the surface concentrations of D, C, and B in the deposited layers. We used 2.5-MeV 3 He + ions, and the protons formed in the nuclear reactions D( 3 He, p) 4 He, 11 B( 3 He, p) 13 C and 12 C( 3 He, p) 14 N were recorded at 150°.…”

“…electron temperature T e and density n e ) have to be known accurately. The slope-ratio method [4] can give a quick picture on the concentrations of composite materials by comparing their LIBS spectra with those extracted from corresponding bulk materials. However, reliable results have been obtained only for samples consisting of 2-3 different elements.…”

The paper deals with the development of laser induced breakdown spectroscopy (LIBS) into an in situ method for studying erosion/deposition processes at the first walls of fusion reactors. To this end, samples extracted from the divertor tiles of ASDEX Upgrade after the 2009 plasma operations were analyzed using LIBS for their composition and the results were compared with other post mortem deposition data. Quantitative depth profiles for the elemental concentrations were extracted from time-resolved LIBS spectra by applying a novel data processing method. In addition, both multiline and multispot averaging procedures were applied to reduce fluctuations in the data. The LIBS concentration profiles matched qualitatively with those given by secondary ion mass spectrometry and quantitatively with the ion-beam data. The deuterium content of the samples could be reliably determined if the surface densities were >10 17 at/cm 2 .

“…Other studies that have reported the use of LIBS for deposit characterization include ones by Malaquias et al, 126 Fantoni et al 127 and Xiao et al 128 All of these papers are related, with many of the same authors appearing on each of them. The work was undertaken on tiles at the International Thermonuclear Experimental Reactor (ITER).…”
