“…Remote analysis of materials in nuclear fusion reactors is another important application for stand-off LIBS [249,257]. During operation of a tokamak fusion reactor, the inner walls of fusion chambers and divertors (plasma-facing components, PFC) are severely interacting with the plasma.…”

Laser-induced breakdown spectroscopy (LIBS) is a rapidly developing technique for chemical materials analysis. LIBS is applied for fundamental investigations, e.g., the laser plasma matter interaction, for element, molecule, and isotope analysis, and for various technical applications, e.g., minimal destructive materials inspection, the monitoring of production processes, and remote analysis of materials in hostile environment. In this review, we focus on the element analysis of industrial materials and the in-line chemical sensing in industrial production. After a brief introduction we discuss the optical emission of chemical elements in laser-induced plasma and the capability of LIBS for multi-element detection. An overview of the various classes of industrial materials analyzed by LIBS is given. This includes so-called Technology materials that are essential for the functionality of modern high-tech devices (smartphones, computers, cars, etc.). The LIBS technique enables unique applications for rapid element analysis under harsh conditions where other techniques are not available. We present several examples of LIBS-based sensors that are applied in-line and at-line of industrial production processes.

“…The inherent advantages of LIBS, such as remote sensing, fast and standalone analysis, three-dimensional analysis of PFCs without any pre-treatment, make LIBS the most suitable technique for the characterization of the wall materials in a tokamak device. 12 Undoubtedly, the development of vacuum LIBS systems is very important for DEMO and next-step fusion reactors. In general, quantitative LIBS analysis is based on the use of calibration curves measuring the intensity to concentration or mass relationship.…”

“…It has been used in a broad range of environments owing to its simplicity of implementation. There are three phases of the materials of sample: Solid, Liquid and Gas, and LIBS is an appropriate approach to study the samples in any of these states [2,3]. When compared to many other methods of elemental analysis, it is…”

In the present work, Laser Induced Breakdown Spectroscopy (LIBS) has been utilized to investigate two forms of aluminum samples, namely Al in the form of the nanoparticles (NPs) and a bulk (pellet). The Al target was irradiated by pulsed Nd-YAG laser with wavelength 1064 nm to produce plasma. The plasm spectrum is analyzed in the wavelength range between 250 nm and 700 nm. Some plasma parameters were calculated, including electron temperature (𝑇 𝑒 ), plasma density (ne) and Debye length (𝜆 𝐷 ) for different laser energies. The temperature of electrons was computed employing the Boltzmann plot technique, and the electrons density was computed utilizing the Stark broadening technique. This work aims to investigate the effect of laser energy on the plasma parameters and the influence of using two different forms of targets on these parameters. It was noted that increasing the laser energy from (400 mJ) to (700 mJ) resulted in an increase in electrons temperature from (0.52 eV) to (0.65 eV) and an increase in electron density from (57.38×10 16 cm -3 ) to (67×10 16 cm -3 ) for the nano aluminum plasma, whereas the electrons temperature increased from (0.52 eV) to (0.59 eV) and the electron density increased from (43.88×10 16 cm -3 ) to (55.05×10 16 cm -3 ) for the bulk aluminum plasma. From the obtained results, it's concluded that using identical laser energies, the electron temperature and electron density of the plasma generated from aluminum in the form of nanoparticles are greater than that generated from aluminum in the bulk form. The differences in the calculated parameters for Al NPs and Al bulk belong to their different structures and morphologies as presented via Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) methods.
