Influence of L-shell dynamics on K-shell yields for imploding krypton Z-pinch plasmas
- Radiation Hydrodynamics Branch, Plasma Physics Division, Naval Research Laboratory, Washington, D.C. 20375 (United States)
The radiative performance of a Z-pinch krypton puff gas heated by a proposed multiterawatt generator is investigated with the aid of a one-dimensional (1-D) non-Local Thermodynamic Equilibrium (LTE) radiation hydrodynamic model self-consistently coupled to a circuit model. For stable loads configured either as cylindrical annular shells or uniform fills, predictions are made for the K- and L-shell soft x-ray emission as a function of the L-shell level structure. The results of numerical simulations show that both the thin annular shell and uniform fill are prolific K- and L-shell radiators. It is also predicted that the L-shell level structure profoundly affects the optimum K-shell soft x-ray yield, as well as the choices for load mass corresponding to optimum emission. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
