The laser-induced breakdown spectroscopy (LIBS) technique has substantial interests for elemental analysis of materials in hostile environments. It is relatively simple to implement in various configurations, it does not require any sample preparation, it is fast and above all, it can be used at remote distance. For these reasons the French Atomic Energy Commission (CEA) has been working on LIBS for two decades, initially for the nuclear sector, and now on different applications which necessitate in situ or online measurements.
In the first part of the seminar, we will give an overview of LIBS activities at CEA, especially on nuclear and micro-LIBS applications. In the second part we will focus on particular research topics of our department. We will present our work on i) in situ analysis of liquid sodium purity to improve the safety of fast nuclear reactors, ii) application of LIBS to nanoparticles measurements for online process control and nano-safety purposes, iii) remote LIBS for qualitative and quantitative analysis of Martian rocks (ChemCam project).
