Abstract
To realize fusion energy in the near future, tritium self-sufficiency is an essential technology in the deuterium-tritium (2H3H) fuel cycle. Thus, high 6‑lithium (6Li) isotope enrichment is desirable to improve the performance of the fusion plant. Additionally, a fast and reliable analysis method for measuring the abundance of Li isotopes is also essential. A novel isotope analysis technique for liquid Li samples, called laser-produced vapor for laser-induced breakdown spectroscopy (LPV-LIBS), has been developed and introduced to measure isotopic abundance. The LPV-LIBS technique combines LPV, in which elements in the liquid samples are vaporized by a high-power pulse laser, and LIBS, in which the laser-induced plasmas are analyzed through optical emission spectroscopy. Li spectra of the 2 s-2p transition line were measured and analyzed, and the results were consistent with those of the reference samples of liquid LiCl employing the developed LPV-LIBS. This is a promising simple and rapid method for measuring the Li isotopic abundance in fusion applications and for other industrial needs.
