Spectral Line Shapes in Plasmas Workshop

The SLSP (Spectral Line Shapes in Plasmas) code comparison workshop will be held in Vienna, Austria, April 2-5, 2012. The workshop is organized by the Weizmann Institute of Science in cooperation with the International Atomic Energy Agency (IAEA).

Motivation

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 inexistant. This workshop purports to fill this gap. By detailed comparison of results for a selected set of case problems, it will be possible to pinpoint sources of disagreements, infer limits of applicability, and assess accuracy.

Therefore, a necessary and sufficient condition for participation would be to submit at least one calculated case.

Topics

• Ion dynamics
• Broadening of Rydberg lines
• Plasma kinetics and line-shapes
• Stark broadening in the presence of external electric and magnetic fields
• Stability and convergence of line-shape calculations

Venue

The workshop will be held at the K+K Maria Theresia Hotel where a block of rooms at the discount flat rate of €122 (single) or €142 (double) are reserved for the duration of the workshop as well as the weekends prior and after the meeting. For reservations, please send email to hotel.maria.theresia@kkhotels.at (attention: Ms. Susanne Eder), and mention the promotion code SLSP2012. The rate includes breakfast, Internet access, use of the wellness center, and taxes. The rooms are to be reserved not later than March 9 2012. A modest registration fee of €70 will be collected on site.
