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.

“…Laser-induced breakdown spectroscopy (LIBS) analysis of nuclear materials is realizing increased interest for actinide mass and isotopic measurements. LIBS offers advantages over conventional solution-based radiochemistry in terms of cost, analytical turnaround, waste generation, personnel dose, and contamination risk [1][2][3][4][5][6]. For example, conventional analysis can require million-fold dilutions of high-activity samples, complicating impurity analyses.…”

Micro-Laser-Induced Breakdown Spectroscopy: A Novel Approach Used in the Detection of Six Rare Earths and One Transition Metal

Laser-induced breakdown spectroscopy (LIBS) was undertaken using an instrument which used a high-powered microscope to deliver the light and tightly focused the low energy laser beam onto the surface of a solid sample. A micro-plasma was generated on the surface of the sample under test even though the amount of energy/pulse from a beam of 532 nm was <1 mJ. Rare earth elements such as europium, gadolinium, lanthanum, neodymium, praseodymium, samarium, and a transition metal, yttrium, were tested. These elements are important in nuclear fission reactions especially for estimation of actinide masses for non-proliferation “safeguards”. Each element was mixed in the graphite matrix in different percentages from 1% to 50% by weight and the LIBS spectra were obtained for each composition as well as after mixing each element in the same amount using oxides of the elements. The data for the 5% mixture of the rare earth elements with graphite powder along with the transition metal has been presented in this article. A micro-LIBS approach was used to demonstrate that these rare earth elements can be identified individually and in a complex mixture in glove boxes in which the microscope LIBS instrument is housed in a nuclear research environment.

“…Laser-induced breakdown spectroscopy (LIBS) has been used to analyze the elemental composition and concentration of many complex environmental samples. Elements from hydrogen to the heavy elements including actinides (uranium, plutonium, americium, neptunium, and thorium) have been investigated [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. LIBS is a highly configurable technique based on the needs of the application.…”

Laser induced breakdown spectroscopy (LIBS) is a rapid atomic emission spectroscopy technique that can be configured for a variety of applications including space, forensics, and industry. LIBS can also be configured for stand-off distances or in-situ, under vacuum, high pressure, atmospheric or different gas environments, and with different resolving-power spectrometers. The detection of uranium in a complex geological matrix under different measurement schemes is explored in this paper. Although many investigations have been completed in an attempt to detect and quantify uranium in different matrices at in-situ and standoff distances, this work detects and quantifies uranium in a complex matrix under Martian and ambient air conditions. Investigation of uranium detection using a low resolving-power LIBS system at stand-off distances (1.6m) is also reported. The results are compared to an in-situ LIBS system with medium resolving power and under ambient air conditions. Uranium has many thousands of emission lines in the 200-800nm spectral region. In the presence of other matrix elements and at lower concentrations, the limit of detection of uranium is significantly reduced. The two measurement methods (low and high resolving-power spectrometers) are compared for limit of detection (LOD). Of the twentyone potential diagnostic uranium emission lines, seven (409, 424, 434, 435, 436, 591, and 682 nm) have been used to determine the LOD for pitchblende in a dunite matrix using the ChemCam test bed LIBS system. The LOD values determined for uranium transitions in air are 409.013 nm (24700 ppm), 424.167 nm (23780 ppm), 434.169 nm (24390 ppm), 435.574 nm (35880 ppm), 436.205 nm (19340 ppm), 591.539 nm (47310 ppm), and 682.692 nm (18580 ppm). The corresponding LOD values determined for uranium transitions in 7 torr CO 2 are 424.167 nm (25760 ppm), 434.169 nm (40800 ppm), 436.205 nm (32050 ppm), 591.539 nm (15,340 ppm), and 682.692 nm (29080 ppm). The LOD values determine for uranium emission lines using the medium resolving power (10000 λ/ λ) LIBS system for the dunite matrix in air are 409.013 nm (6120 ppm), 424.167 nm (5356 ppm), 434.169 nm (5693 ppm), 435.574 nm (6329 ppm), 436.205 nm (2142 ppm), and 682.692 nm (10741 ppm). The corresponding LOD values determined for uranium transitions in a SiO 2 matrix are 409.013 nm (272 ppm), 424.167 nm (268 ppm), 434.169 nm (402 ppm), 435.574 nm (1067 ppm), 436.205 nm (482 ppm), and 682.692 nm (720 ppm).The impact of spectral resolution, atmospheric conditions, matrix elements, and measurement distances on LOD are discussed. The measurements will assist one in selecting the proper system components based upon the application and the required analytical performance.
