  The Laboratory Astrophysics program employing the Lawrence Livermore National
Laboratory (LLNL) Electron Beam Ion Trap (EBIT) has been providing useful
atomic data in support of the x-ray missions Chandra and XMM-Newton. Major
achievements have been made for Fe L-shell ions in hot, collisional plasmas,
relevant to stellar coronae, supernova remnants, elliptical galaxies, and
galaxy clusters. Measurements for L-shell ions of other cosmiscally important
elements are also required, some of which are in the LLNL EBIT pipeline. On the
other hand, data for inner-shelll excited lines relevant to photoionized
plasmas near accretion sources are largely lacking. Even the wavelengths of
these lines are only poorly known, which severely limits their use for
diagnostics, despite the great potential.
