    Abstract

    Laser-induced breakdown spectroscopy (LIBS) is a potential method for in situ monitoring of deposition and retention in fusion devices and is developed with the aim of being integrated in the diagnostics system of ITER. The inner divertor of the ITER-like wall of JET was studied by LIBS to show the applicability of the method in JET and ITER. The elemental depth profiles agreed with those given by earlier SIMS measurements. Deuterium was detected in the deposited layers and successfully distinguished from hydrogen. The poloidal patterns of the retained deuterium and deposited beryllium were also in line with the SIMS results with the largest deposition and retention taking place on the top part of Tile 1 and bottom part of Tile 3. The results of these studies support LIBS as a promising in situ solution to replace the present post mortem methods in monitoring metallic deposited layers.
