A fiber-coupled, acoustic-wave-assisted (AW) microchip laser-induced breakdown spectroscopy (mLIBS) system was developed to analyze the elemental composition and surface imaging. In this study, we measured the dependence of sample temperature and laser ablation angle (LAA) on the laser-induced plasma–optical emission (LIP–OE) and LIP–acoustic signal (LIP–AS). The intensity of the LIP–OE and ablated mass at three different temperatures and eight different LAAs were estimated using a zirconium sample. Simultaneously, we investigated the LIP–AS amplitude, propagation speed, and shape by synchronizing the AW-mLIBS system with a high-speed camera. The results revealed that the LIP–OE increases with increasing temperature and is unaffected by LAA up to 40° because the amount of the ablated mass was similar to the plasma. Additionally, no considerable variation in plasma temperature was obtained using the Boltzmann method over the sample temperature. However, the propagation speed of the LIP–AS differs with temperature but has marginal angular dependence because the LIP–AS propagates as semispherical. Furthermore, no considerable changes were observed in the LIP–AS amplitude up to 100°C, and the LAA showed a similar tendency to that of the LIP–OE.

This study aims to develop ultralong fiber-optic cable (FOC) coupled microchip laser – induced breakdown spectroscopy (mLIBS) to reveal the elemental distribution and local composition of nuclear fuel debris in an accident-damaged reactors at Fukushima Daiichi Nuclear Power Station (FDNPS). Currently at FDNPS, the distance between the area where humans can safely work in a sufficient space and the nuclear fuel debris is expected to be >100 m. Therefore, it becomes crucial to analyze the light transmittance performance of FOC-coupled mLIBS systems over such long distances in a high-radiation environment. Therefore, this study focuses on the influence of gamma radiation dose and FOC length on the transmittance of the visible and near-infrared (NIR) wavelengths through FOCs. Compared with an FOC with low-OH groups, that with high-OH groups exhibits better light transmittance performance in both wavelength regions in a high-radiation environment. Furthermore, the light transmittance performance of the high-OH FOC extended up to 500 m in length is tested in a radiation-free environment. From the measurement results, the maximum FOC length for microchip crystal oscillation is estimated to be >800 m, although attenuation is observed with the increase in FOC length. Finally, we analyze the ultralong FOC–coupled mLIBS system through the detection of gadolinium (Gd) in mixed oxide samples. The strong emission lines of Gd were only available in the visible wavelength region. Therefore, quantitative analysis of Gd is successfully performed in the visible region using the mLIBS system coupled with up to 300-m-long FOCs, with the limits of detection being between 0.1% and 0.2%.
