Collisionalradiative modeling of tungsten at temperatures of 1200–2400 eV
We discuss new collisionalradiative modeling calculations of tungsten at moderate temperatures of 1200 to 2400 eV. Such plasma conditions are relevant to ongoing experimental work at ASDEX Upgrade and are expected to be relevant for ITER. Our calculations are made using the Los Alamos National Laboratory (LANL) collisionalradiative modeling ATOMIC code. These calculations formed part of a submission to the recent NLTE8 workshop that was held in November 2013. This series of workshops provides a forum for detailed comparison of plasma and spectral quantities from NLTE collisionalradiative modeling codes. We focus on the LANL ATOMIC calculations for tungsten that were submitted to the NLTE8 workshop and discuss different models that were constructed to predict the tungsten emission. In particular, we discuss comparisons between semirelativistic configurationaverage and fully relativistic configurationaverage calculations. As a result, we also present semirelativistic calculations that include finestructure detail, and discuss the difficult problem of ensuring completeness with respect to the number of configurations included in a CR calculation.
