Review of the 1st Spectral Line Shapes in Plasmas code comparison workshop
نویسنده
چکیده
A review is given of the first workshop dedicated to the detailed comparison of various approaches to the calculation of spectral line shapes in plasmas. A standardized set of case problems was specified in advance, together with the prescribed atomic data and assumptions to be used. In this brief review, motivations for the case problems chosen are outlined, followed by a discussion of selected results. Plans for the next workshop are discussed in the conclusion. 2013 Elsevier B.V. All rights reserved.

Quasicontiguous frequency-fluctuation model for calculation of hydrogen and hydrogenlike Stark-broadened line shapes in plasmas.
We present an analytical method for the calculation of shapes of Stark-broadened spectral lines in plasmas, applicable to hydrogen and hydrogenlike transitions (including Rydberg ones) with Δn>1. The method is based on the recently suggested quasicontiguous approximation of the static Stark line shapes, while the dynamical effects are accounted for using the frequency-fluctuation-model approach...
متن کاملDevelopment of a tunable Fabry-Perot etalon-based near-infrared interference spectrometer for measurement of the HeI 2³S-2³P spectral line shape in magnetically confined torus plasmas.
In magnetically confined torus plasmas, the local emission intensity, temperature, and flow velocity of atoms in the inboard and outboard scrape-off layers can be separately measured by a passive emission spectroscopy assisted by observation of the Zeeman splitting in their spectral line shape. To utilize this technique, a near-infrared interference spectrometer optimized for the observation of...

We present an analytical method for the calculation of shapes of Stark-broadened spectral lines in plasmas, applicable to hydrogen and hydrogen-like transitions (including Rydberg ones). The method is based on the recently suggested quasi-contiguous approximation of the static Stark line shapes [E. Stambulchik, and Y. Maron, J. Phys. B: At. Mol. Opt. Phys. 41, 095703 (2008)], while the dynamica...
متن کاملForward Modeling of EUV and Gyrosynchrotron Emission from Coronal Plasmas with FoMo
The FOMO code was developed to calculate the EUV and UV emission from optically thin coronal plasmas. The input data for FOMO consists of the plasma density, temperature and velocity on a 3D grid. This is translated to emissivity on the 3D grid, using CHIANTI data. Then, the emissivity is integrated along the line-of-sight (LOS) to calculate the emergent spectral line for synthetic spectrometer...

Results and methods are given for the investigation of hot laboratory and astrophysical plasmas parameters in a soft X-ray region 1 = 1-40 A. Line spectra of multiply charged ions are usually studied exper~mentally, and relative Intensities of spectral lines are measured. Achievements of modern physics of electronion collisions and theoretical spectroscopy make it possible to obtain for transie...
