Abstract :
The performance of a double metal puff Z-pinch system has been experimentally studied. The arc-produced plasma shells were compressed by using a 450-kA 450-ns driver. The energy of the Al K-shell radiation emitted by the plasma for 7 ns was 32 J/cm. Comparison of the experimental data with predictions of a numerical simulation based on equations of 1-D two-temperature radiation magnetohydrodynamics has shown that the predicted K-shell radiation energy is close to that found experimentally.
