“…Therefore, corrections must also consider these effects. Other future work may include the analysis of spectra relevant to LIBS in other high-radiation environments, such as for spent fuel cask monitoring [ 38 , 39 ].…”

Increased absorption of optical materials arising from exposure to ionizing radiation must be accounted for to accurately analyze laser-induced breakdown spectroscopy (LIBS) data retrieved from high-radiation environments. We evaluate this effect on two examples that mimic the diagnostics placed within novel nuclear reactor designs. The analysis is performed on LIBS data measured with 1% Xe gas in an ambient He environment and 1% Eu in a molten LiCl-KCl matrix, along with the measured optical absorption from the gamma- and neutron-irradiated low-OH fused silica and sapphire glasses. Significant changes in the number of laser shots required to reach a 3σ detection level are observed for the Eu data, increasing by two orders of magnitude after exposure to a 1.7 × 1017 n/cm2 neutron fluence. For all cases examined, the spectral dependence of absorption results in the introduction of systematic errors. Moreover, if lines from different spectral regions are used to create Boltzmann plots, this attenuation leads to statistically significant changes in the temperatures calculated from the Xe II lines and Eu II lines, lowering them from 8000 ± 610 K to 6900 ± 810 K and from 15,800 ± 400 K to 7200 ± 800 K, respectively, for exposure to the 1.7 × 1017 n/cm2 fluence. The temperature range required for a 95% confidence interval for the calculated temperature is also broadened. In the case of measuring the Xe spectrum, these effects may be mitigated using only the longer-wavelength spectral region, where radiation attenuation is relatively small, or through analysis using the iterative Saha–Boltzmann method.

“…A major benefit of LIBS is the ability to utilize fiber-optics for laser delivery and emission collection during analysis. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] This section reviews previous reports of fiber-optic (FO)-LIBS, including configurations, results, and lessons learned. This information will be crucial for establishing an in-house FO-LIBS system.…”

“…Fobar et al 22 used a Nd:YAG 1,064 nm laser with a 10 ns pulse width. Reportedly, the 1,064 nm wavelength gave a much higher signal-to-noise ratio for a peak of interest than the 532 nm harmonic.…”

“…Laser-induced breakdown spectroscopy (LIBS) is based on the spectral analysis of element-specific plasma emission by focused laser onto a target material [2,3] and has been applied as a qualitative and quantitative analytical tool to various fields including environmental analysis [4]. Among previously applied techniques for nuclear inspection [5][6][7][8][9], fiber-optic laser-induced breakdown spectroscopy (FO-LIBS) is also considered as one of the promising methods [10][11][12][13], especially to remotely inspect inside the reactor core and analyze the properties of the debris [14].…”
