A fully self-consistent one-dimensional ion beam-slab interaction model has been developed which describes the slowing down of the beam, the hydrodynamic response and ionization dynamics of the slab, and detailed radiation emission and transport. An extensive atomic level structure with collisional radiative ionization dynamics is employed in conjunction with a hybrid radiation transport scheme which consists of a multifrequency formalism for continuum transport and a probabilistic treatment for line transport. It is found that beam deposition and slab response depend strongly on radiation transport within the slab. Temperature and density profiles and emission spectra are presented.
