Spectral Line Shapes in Plasmas Workshop (SLSP 3)

The 3rd SLSP code comparison workshop will be held in Marseille, France, at the Balladins Saint-Charles hotel, March 2-6, 2015.

The workshop is organized by the PIIM laboratory - Aix Marseille University - CNRS - in cooperation with the International Atomic Energy Agency (IAEA).

Line-shape analysis is arguably one of the most important tools for diagnostics of both laboratory and space plasmas. Evidently, its reliable implementation requires sufficiently accurate calculations. The Stark broadening is the most computationally challenging contribution, with other factors (such as the Zeeman and Doppler effects) further complicating the calculations.

Except for limiting cases, line-shape calculations imply a usage of computer codes of varying complexity and requirements of computational resources. However, studies comparing different computational and analytical methods are almost nonexistent. This workshop purports to fill this gap. By detailed comparison of results for a selected set of case problems, it becomes possible to pinpoint sources of disagreements, infer limits of applicability, and assess accuracy.

Ion dynamics
Ionization potential depressions and line shapes
Large-scale line-shape calculations
Stark broadening in the presence of external electric and magnetic fields
Stability and convergence of line-shape calculations

A necessary and sufficient condition for participation is to submit at least one calculated case.
