Laser-induced plasmas are versatile physical systems with applications in a wide range of fields, spanning from materials and biomedical sciences to environmental and food safety to extraterrestrial planet exploration, and more. Making the most of this broad set of applications requires a detailed knowledge of the plasma parameters and elementary processes responsible for the generation and...
In JET and future fusion reactors, thick co-deposited layers will be formed on their inner walls during extended plasma operations. Experiments in present-day fusion devices indicate these layers to consist of eroded plasma facing materials, various impurities in the edge parts of the fusion plasma, and actual plasma fuel species deuterium and tritium. Monitoring the inventory of the...
In this work we report on the chemical characterization of metallic tiles of interest for nuclear fusion technology by using the Laser-Induced Breakdown Spectroscopy (LIBS) technique. The LIBS system used was designed to be compact and light, equipped with a sub-ns laser and suitable to be mounted on the Joint-European-Torus (JET) robotic arm. The coatings, composed of tungsten (W), Molybdenum...
