X-Ray Laser Related Line Identifications of Neon-Like Ions
Abstract
These two papers report the analysis of high resolution, time resolved spectra from the PLT tokamak plasma. Data was collected on a large number of PLT discharges. The spectra from the highly-charged ions from the wall material (Fe, Ni, Cr, and Ti) were recorded, and spectra from the injected elements, Fe, Ni, Zn, Ge, Se, and Mo were produced using the laser ablation techniques. A very precise wavelength scale was established using well-known reference lines. A number of transitions of the type Delta n = O and terminating on levels within the ground configurations were identified. The primary purpose was to produce an abundance of Nw-like ions in the PLT discharge and to search for Ne-like transitions of the type 3s-3p. The F-like and Na-like ionization stage was certainly produced. However, the 3s-3p transitions were very weak, and conclusive identifications could not be made. In general, the ground state transitions are intense in the PLT plasma, and transitions between excited states are weaker. It was found that the PLT tokamak with its variety of very sophisticated diagnostic instruments, and with very reproducible and higher temperature plasma, is an extremely good device for spectroscopic and atomic physics studies.
