Abstract : This report details the work of the Radiation Hydrodynamics Branch conducted in FY94 with respect to several critical problems concerning (1) the analysis of experimental z-pinch data, (2) the optimization of PRS performance on existing pulse-power generators, and (3) the design and analysis of advanced simulator z-pinch experiments. Separate sections describe progress in (1) the analysis of Physics International Inc. (PI) Al/Mg mixture experiments, (2) the design and analysis of Al experiments at PI that produced a doubling of previous K-shell yields, (3) an analysis of Saturn data that correlated x-ray yields with the mass fraction of plasma that produced the radiation, (4) proposals for new PRS experiments that should increase mass participation, decrease plasma opacity, and increase x-ray yields and simulation fidelity, (5) the identification of new issues for scaling K-shell yields to higher photon and output energies, (6) calculations of the effects of MITL losses on power flow to PRS loads in advanced multi-mega-ampere simulators, (7) the development of diagnostics for determining the opacity of line emission in PRS plasmas, and (8) the development of diagnostics to measure the rate of ionization through the L-shell of moderate atomic number plasmas such as nickel or selenium.
