“…Notably, LA-OES proves practical in detecting isotopic shifts of elements including U [21][22][23][24][25][26][27]. Reported U detection limits employing LA-OES are on the order of parts per million (ppm) [20,28,29]. However, previous investigations also suggest that the U signal varies significantly with ambient conditions using different LA spectrometric techniques [30].…”

This study employs laser ablation (LA) to investigate mechanisms for U optical signal variation under various environmental conditions during laser absorption spectroscopy (LAS) and optical emission spectroscopy (OES). Potential explored mechanisms for signal quenching related to ambient conditions include plasma chemistry (e.g., uranium oxide formation), ambient gas confinement effects, and other collisional interactions between plasma constituents and the ambient gas. LA-LAS studies show that the persistence of the U ground state population is significantly reduced in the presence of air ambient compared to nitrogen. LA-OES yields congested spectra from which the U I 356.18 nm transition is prominent and serves as the basis for signal tracking. LA-OES signal and persistence vary negligibly between the test gases (air and N 2 ), unlike the LA-LAS results. The plume hydrodynamic features and plume fundamental properties showed similar results in both air and nitrogen ambient. Investigation of U oxide formation in the laser-produced plasma suggests that low U concentration in a sample hinders consistent detection of UO molecular spectra.

“…Trace concentrations of U have been detected, with detection limits determined to be in the parts per million (ppm) range. [10][11][12] Various ambient environments have also been explored for detection of bulk SNMs, including air and Ar at various pressures. 13 As U has a very complex atomic structure with closely packed emission lines, high spectral resolution is a crucial figure of merit.…”

Detection of uranium and other nuclear materials is of the utmost importance for nuclear safeguards and security. Optical emission spectroscopy of laser-ablated U plasmas has been presented as a stand-off, portable analytical method that can yield accurate qualitative and quantitative elemental analysis of a variety of samples. In this study, optimal laser ablation and ambient conditions are explored, as well as the spatio-temporal evolution of the plasma for spectral analysis of excited U species in a glass matrix. Various Ar pressures were explored to investigate the role that plasma collisional effects and confinement have on spectral line emission enhancement and persistence. The plasma-ambient gas interaction was also investigated using spatially resolved spectra and optical time-of-flight measurements. The results indicate that ambient conditions play a very important role in spectral emission intensity as well as the persistence of excited neutral U emission lines, influencing the appropriate spectral acquisition conditions.

With advantages of in-situ, micro-damage, rapid analysis, laser-induced plasma spectroscopy (LIPS) has made a great progress in nuclear analysis and detection. The instrumentation of LIPS mainly consists of laser system, optical system and analysis system. Applications of LIPS to nuclear industry are reviewed, such as international nuclear safeguard, nuclear materials analysis, process monitoring and hazard materials detection.
