Abstract:
Li pellet injection has provided a complex plasma with a large fraction of Li ions, which is characterized by intense emissions from Li I and III. The spatial profiles of the fully ionized Li^3+ ions are measured by charge exchange recombination spectroscopy with a resolution of 13 mm, and the local decay time of the injected Li ion has been estimated. The spectral profile of the charge exchange recombination line of Li^2+ from n=5 to n=4 shows a complicated structure, which depends on Li^3+ density. The effects on other intrinsic impurities and recycled Li are also discussed.
