Abstract

International audience; In preparation for the SuperCam/Mars Microphone scientific investigation, the acoustic signal associated with the plasma formation during Laser-Induced Breakdown Spectroscopy (LIBS) experiment is studied with regard to the shot-to-shot evolution of the laser induced crater morphology and plasma emission lines. A set of geological targets are depth profiled using a specifically designed LIBS setup coupled with acoustic test bench under ambient terrestrial atmosphere. Experiments confirm that the decrease of the acoustic energy as a function of the number of shots is well correlated with the target hardness/density and also demonstrate that the acoustic energy can be used as a remote tracer of the ablated volume of the target. Listening to LIBS sparks provides a new information relative to the ablation process that is independent from the LIBS spectrum.

Abstract

Fig. 5. The degree of local order (i.e., packing density) at the position of each particle in a numerical simulation when the small particle concentration is 10%. Grain boundary (GB) regions determined using the algorithm of Berardi et al. (2010). Black signifies near-hexagonal particle packing with w6 close to 1. Grey and white correspond to more disordered packing with w6 < 0.7 (i.e., GB regions). See Eq. (1) for the definition of w6. The locations of the small (2 mm) particles are all marked with an . The laboratory experiment results are not shown here, but in both the experiments and the numerical simulations the small particles are almost all located in grain boundaries. Particles are not drawn to scale.
