Application of CHIANTI to Solar-B

CHIANTI (http://wwwsolar.nrl.navy.mil/chianti.html) has been
developed to support the interpretation of solar and
astrophysical spectroscopic measurements. The most recent
release, version 5.0 (Landi et al., 2005) presenet an
improvement over previous versions by including new large
scale datasets for Fe ions from Fe XVII to Fe XXIV for X-ray
emission and improved atomic data for EUV line emission. We
will demonstrate how this can be applied to the analysis of
XRT and EIS data, in particular. For example, new
excitation rates for Fe XII have resolved a long standing
problem in the use of Fe XII line ratios as accurate density
diagnostics. Current work involves improvements to
ionization and recombination rates which will also be useful
in the interpretation of Solar-B data.
