Spectroscropy of middle charge state high-z ions in the ultraviolet for plasma diagnostics
- Auburn Univ., AL (United States)
The quest for the creation of an economically feasible thermonuclear fusion energy reactor is sttill active after many decades of research. Modern machines produce plasmas which are both hotter and more dense than those created 30 years ago and future devices promise to continue this trend. Paramount to this research is the capability to adequately measure certain parameters of the plasma such as temperature, density, impurity concentration and radiation loss. This dissertation reports three sets of spectroscopic measurements from intermediate charge state of high-Z ions, which have been performed at the Electron Beam Ion Trap (EBIT) facility of the Lawrence Livermore National Laboratory, relevant to the development of spectral plasma diagnostics and to the understanding of radiative energy loss from heavy impurity ions of today's and future fusion devices: measurements of W radiation from 40 - 85 A, precision measurements along the Cu isoelectric sequence, and UV spectroscopy of Ti-like W. The results are also compared to the best available theoretical calculations.
