New and Updated Atomic Databases at NIST*

We present a number of updated and newly developed databases at NIST. New spectral lines compilations for all ionization stages of Na and Mg and other data sets were recently added to the Atomic Spectra Database (currently version 3.0.3) which now contains data on 75,000 energy levels and about 130,000 spectral lines for all elements up to Z=99. A new database (SAHA) containing benchmark data for plasma populationkinetics modeling has been released in its beta version. SAHA database presents various selection and graphical tools for comparison of results calculated with the most advanced collisional-radiative computer codes. Finally, we report on a new comprehensive bibliographic database covering references on energy levels, spectral linesm and line shapes and broadening.
