Carbon‐Based Nanostructured Film Materials for High‐Intense Laser‐Matter Interaction Experiments

Abstract

In this paper, a new synthesis of carbon‐based nanostructured films for application as plasma facing materials during high‐intense laser‐matter interaction experiments is presented. The materials are produced using a Polyethylene glycol (PEG) matrix, nanostructured with multiwalled carbon nanotubes, or multi‐layer graphene flakes producing a 250 μm thick film. The films are deposited onto typical materials used in harsh environments such as plasma facing materials. These PEG reinforced materials are irradiated by laser‐accelerated particles and by an in‐air plasma, both are techniques that have shown to heavily stress and damage materials used in laser‐matter interaction experiments. The authors observe that the chemical structure of the PEG reinforced materials, when irradiated by both techniques, stays unchanged. However, one can see that the PEG layer adds considerable longevity to the underlying materials, making it more robust against erosion and ablation occurring during its operation.

Combined laser-based X-ray fluorescence and particle-induced X-ray emission for versatile multi-element analysis

“…The wide-range use of these laser-driven particle sources has triggered the construction of a series of laser facilities with dedicated laser-based beamlines (to cite a few of them: ALLS 1 in Canada, APOLLON 2 in France, VEGA 3 in Spain). Among the many applications, laser-based proton beams can be utilized for producing bright ultra-short neutron sources 4 , in medicine 5 , for picosecond metrology 6 , for stressing and testing materials 7 , 8 , and lately also in Ion Beam Analysis (IBA) 9 – 12 . Within the IBA techniques, we can name the Particle-Induced X-ray Emission (PIXE), a particle-based spectroscopy technique used for retrieving the elements of a material.…”

Detection of laser-plasma experiment radiation using nanoparticle coatings as fluorescent sensors

“…Many groups are currently investigating the effect of intense laser-matter interaction to the surrounding environment, which comprises the vacuum chamber and auxiliaries (e.g., electronic devices, imaging detectors, etc.). Several studies have focused on the design and realization of new materials that can act as more resistant plasma-facing materials [10][11][12][13][14][15], on measurements and diagnostics/sensors able to withstand the presence of ionizing and electromagnetic radiation (Electro Magnetic Pulses (EMP)) produced and dispersed during the experiment [16,17], or on how to mitigate its impact, [18][19][20]. Luminescence properties of point defects in insulating and nanomaterials have already been successfully used as detectors for measuring radiation [21][22][23].…”

Preparation of graphene on SiC by laser-accelerated pulsed ion beams*

“…[9] In recent three years, laser-accelerated ion beams have begun to be applied to the field of material science that can produce strong mechanical and thermal damages to the irradiated objects in a short period of time, or test the radiation resistance of materials under extreme conditions. [10,11] The intense and rapid de-position of ion energy will also change the surface structure of the materials and realize the ultra-fast synthesis of some new materials. [12][13][14] As exploring new applications of laser-accelerated pulsed ion beams in new materials science, graphene, a twodimensional material with many excellent optical, electrical, thermal and mechanical properties, has already received more and more extensive researches.…”
