Advances in the understanding of complex phenomena depend on new well-diagnosed experiments. These cutting-edge experiments require state-of-the-art modeling capabilities. X-ray spectroscopy and imaging have been widely used in the plasma physics community as powerful diagnostics tools. Spectroscopy is a classic example of a non-interfering probe. Fundamental information on plasma conditions can be obtained by analyzing line emission or absorption spectra. Detailed modeling of spectral formation can provide information on the ionization balance, charge state distributions, temperatures, and densities. Over the years, Prism Computational Sciences, Inc. has developed a variety of modeling capabilities to study radiative properties of matter. I will briefly describe those models and their applications to a wide range of experiments: laboratory astrophysics, thermonuclear fusion, short-pulse laser plasmas. I would also like to discuss an opportunity for collaboration with the nuclear physics community: interdisciplinary projects can be very successful. Possibilities may include planning experiments for diagnostics of charge state evolution, spectroscopy of highly-charged ions, identification of reaction products, studying the importance of various atomic processes: excitation, ionization, electron capture, etc.
