PrismSPECT is an easy-to-use spectral analysis tool that simulates the spectral properties of LTE (local thermodynamic equilibrium) and non-LTE plasmas. It computes atomic level populations and ionization fractions for volume elements of uniform temperature and density, and computes detailed emission and absorption spectra. Spectra can be convolved with instrumental broadening to facilitate direct comparisons with experimental spectra. Spectra can readily be computed and displayed for a grid of densities and temperatures. It has been designed specifically for ease of use, and is suitable for graduate and advanced undergraduate research projects in plasma spectroscopy. SPECT3D is a multi-D spectral analysis and imaging code used to compute detailed spectra and simulated images. It can read in data from 1-D and multi-D hydrodynamics calculations - consisting of temperatures and densities for a grid of volume elements - and compute spectra and filtered images for LTE and non-LTE plasmas. By computing the radiation incident on a user-specified virtual detector plane, it allows for direct comparisons with experimental images and spectra. Both codes utilize a comprehensive atomic database so that very detailed spectra can be computed and compared with experimental data. We will present sample calculations and comparisons with experimental data.
