SPECT3D Imagining and Spectral Analysis Code: Enhancements and New Capabilities

SPECT3D is a collisional-radiative spectral analysis package used to compute detailed emission, absorption and X-Ray Thomson Scattering (XRTS) spectra, as well as filtered images, for multiple 1D, 2D, and 3D geometries. SPECT3D computes LTE and non-LTE populations using detailed atomic physics models. We present new improvements to SPECT3D, including improved radiation transport in 2D geometries, full implementation of atomic data produced by the Flexible Atomic Code (FAC), a new model for calculating Stark line widths, improvements and new features for XRTS, and general speed improvements.
