title: L-shell spectroscopy of Au as a temperature diagnostic tool.
abstract: In order to develop plasma diagnostic for reduced-size hot Hohlraums under laser irradiation, we have studied the L-shell emission from highly charged gold ions in the SuperEBIT electron beam ion trap. The resolving power necessary to identify emission features from individual charge states in a picket-fence pattern has been estimated, and the observed radiation features have been compared with atomic structure calculations. We find that the strong 3d(5/2)-->2p(3/2) emission features are particularly useful in determining the charge state distribution and average ion charge Z, which are strongly sensitive to the electron temperature.
