| Experimental rig uses a microscope arrangement to allow a very small spot size. Approximately 1um resolution was achieved by careful work, however this did not yield sufficient plasma size/intensity for LIBS. However, a 3um laser spot size did provide a sufficiently intense plasma plume for LIBS analysis. The configuration also makes use of a glove box filled with Ar around the analysis. Quantitative analysis of CeO2/UO2 ceramic pellets were performed. Also surface mapping of Al and Steel alloys | |||||
