Title: NUMERICAL SIMULATIONS OF CONVERGING SHOCKS IN PULSED POWER DRIVEN EXPERIMENTS

Abstract

The final shot of the current Near Term Liner Experiment (NTLX) series occurred on September 29, 2000. Utilization of a pulsed power source with a standardized liner/target ''cartridge'' produced a uniform implosion to drive hydrodynamic experiments. Diagnostics showed that high quality data of shock propagation can be obtained from pulsed power liner drivers as in the current NTLX series. Very good agreement in calculating shock locations was obtained between the codes used to model the NTLX series, RAGE and RAVEN. RAVEN also accurately predicts liner/target impact as measured by B-Dot probes. Large differences are observed between the calculated and measured positions of converging shock waves even in simple geometrical configurations. Liner/target impact is accurately calculated and similar results are produced for shock velocities in Lucite. RAGE and RAVEN use different hydrodynamic algorithms, yet agree, this focuses current efforts on EOS issues within the outer tin target to resolve discrepancies. Further diagnostics covering shock breakout from the outer tin target and shock propagation shortly thereafter would be highly beneficial.
